These tiny solar cells work using a process much like photosynthesis--photons hit the dye, electrons are released and then passed on to a special conductive material that harvests the electricity. They're designed to work in lower light conditions than traditional solar cells and are powerful enough to power small electronics up to the size of a keyboard.
The idea is that these tiny solar cells could replace small batteries for low-energy electronics--they last significantly longer and produce 90% fewer emissions per unit of energy than traditional batteries. Solar cells also remove the emissions from shipping and replacing batteries, although there are potentially some additional environmental costs associated with their production.
This is a really cool step towards having electronics that are powered by renewable energy on an individual level rather than requiring batteries.
Recyclable solar cells developed by Swedish researchers use only water instead of toxic chemicals, potentially solving a major waste problem
by Elena Kryvoshei, Mon 30 Jun 2025
Scientists have developed recyclable solar cells that use only water, eliminating the need for toxic chemicals and potentially addressing a major environmental challenge in the solar industry.
Swedish researchers have developed a method for fully recycling advanced solar cells using only water, potentially addressing a significant environmental challenge as the solar industry continues its rapid expansion.
The new technique could help address concerns about waste from perovskite solar panels, which are more efficient than traditional panels but difficult to recycle.
Solar energy has experienced significant growth in recent years, with the global market expanding at a rate of around 24% annually over the past decade. This growth is expected to continue, with industry estimates suggesting the market will triple in size by 2028.
Part of this expansion will come from newer perovskite solar cells, which can convert up to 25% of solar energy into electricity. Traditional silicon-based cells typically achieve an efficiency of only 15-20%.
However, these high-performing perovskite cells have presented a significant recycling challenge. Until now, breaking them down required toxic chemicals that could harm the environment.
Researchers from Linköping University in Sweden have published findings in the journal Nature that could change this situation. They’ve developed a water-based method that completely breaks down perovskite solar cells without using harmful chemicals.
“We can recycle everything—covering glasses, electrodes, perovskite layers, and also the charge transport layer,” said Xun Xiao, a postdoctoral student and co-author of the research.
Professor Feng Gao, another paper co-author, emphasized the importance of considering recycling from the start: “If we don’t know how to recycle them, maybe we shouldn’t put them on the market at all.”
Instead of toxic chemicals, the researchers created a water-based solution containing three additives: sodium acetate, sodium iodide, and hypophosphorous acid.
Each ingredient serves a specific purpose in the recycling process. Sodium acetate helps separate the cell’s materials, while sodium iodide helps reform the perovskite crystals so they can be reused in new solar cells. Hypophosphorous acid keeps the solution stable.
The process involves heating water to 80 degrees Celsius (176 degrees Fahrenheit) for 20 minutes before submerging the solar cell. After the cell breaks down, the team separates the recycled perovskite crystals using a centrifuge spinning at 5,000 rotations per minute for three minutes.
The most impressive aspect of this breakthrough is that solar cells made from these recycled materials maintain the same efficiency as the original cells. This means manufacturers could potentially reuse the same materials multiple times without losing performance.
This development addresses a key sustainability concern in the solar manufacturing industry. While solar power itself produces clean energy, the production of solar panels requires the mining of critical minerals from around the world. These materials are often difficult to source and have their own environmental impact.
The ability to recycle these materials multiple times could reduce the need for new mining operations and lower the overall environmental footprint of solar energy.
The creation of fully recyclable solar cells could also help bring down solar energy prices in the long term. By reusing expensive materials instead of constantly mining new ones, manufacturers might reduce production costs, making solar power even more competitive with fossil fuels.
Currently, the solar industry faces significant recycling challenges. According to the International Renewable Energy Agency, only about 10% of solar panels worldwide are recycled properly. The vast majority end up in landfills where their valuable and sometimes toxic materials can’t be recovered.
By 2050, experts predict that solar panel waste could reach 78 million tons globally. This makes the development of recyclable solar cells increasingly urgent from both environmental and economic perspectives.
The cost difference between traditional recycling methods and this new water-based approach is substantial. While conventional recycling of perovskite solar cells requires expensive chemical solvents and specialized disposal processes that can cost up to $25-30 per panel, early estimates suggest the water-based method could reduce these costs by 60-70%.
Solar panel prices have already dropped significantly in recent years, helping drive the industry’s growth despite political opposition from some quarters. The Trump administration had voiced opposition to solar development, but the industry continued to expand regardless.
Perovskite solar cells represent the next generation of solar technology due to their higher efficiency. They can convert a quarter of the sun’s energy that hits them into usable electricity, significantly better than most panels currently on rooftops around the world.
Their main drawback has been the end-of-life disposal issues. Unlike many other products, solar panels contain specialized materials that need proper handling when they’re no longer useful.
The water-based recycling method developed by the Swedish researchers represents a potential solution to this problem. By making the entire recycling process less toxic and more efficient, they’ve addressed one of the few remaining environmental concerns about solar energy.
The regulatory landscape for solar panel recycling varies widely across the globe. The European Union leads with its Waste Electrical and Electronic Equipment (WEEE) Directive, which requires manufacturers to take back and recycle solar panels at the end of their life.
In the United States, most states lack specific regulations for solar panel disposal; however, California has classified them as universal waste, requiring special handling. China, the world’s largest solar producer, has recently begun developing national standards for recyclable solar cells and the disposal of solar panels.
If scaled up successfully, this technology could help ensure that the growing solar industry remains truly sustainable throughout the entire lifecycle of its products.
The findings come at a critical time for renewable energy. As more countries and companies commit to reducing carbon emissions, the demand for solar power continues to increase. Ensuring this growth occurs in an environmentally responsible manner is crucial for effectively addressing climate change.
By developing methods to recycle the most advanced solar cells fully, researchers are helping ensure that clean energy solutions don’t create new environmental problems along the way.
Covering 10% of the world’s hydropower reservoirs with ‘floatovoltaics’ would install as much electrical capacity as is currently available for fossil-fuel power plants. But the environmental and social impacts must be assessed.
“The floatovoltaic industry is poised to expand rapidly. Science and policy must move equally fast to ensure that this use of the world’s reservoirs is sustainable & equitable.”
Some valuable insight to consider today as we fight to end fossil fuel use.
Imagine creating solar panels without relying on materials in short supply and adopting an eco-friendlier production process. And at the same time boosting efficiency? Enter perovskite tandem solar cells—an innovation that has long held the promise of revolutionizing the solar energy landscape. But where are they in their development, and could they truly represent the future of solar panel technology?
Thanks go to Frank Nowroth (Oxford PV) who gave insights into commercial-scale deployment of tandem solar cells and to Sum Tze Chien (NTU Singapore) for additional background on tandem solar cells encapsulation.

The White House announced a 5-year, $5 billion investment in electric vehicle charging stations around the country
The U.S. Departments of Energy and Transportation announced a plan to distribute $5 billion over the next five years to install electric vehicle (EV) charging stations around the country.
It’s a part of the Biden Administration’s goal to work towards having 500,000 EV chargers by 2030. Currently, the U.S. only has about 100,000 charging stations.
Up from just 2,000 in 2020, researchers counted nearly 250,000 monarch butterflies in California in 2021
In recent years, the number of monarch butterflies migrating through California have fallen to concerning numbers. In a new report, researchers saw a hopeful trend — they counted nearly 250,000 monarch butterflies in California, the highest in 5 years, and up from just 2,000 in 2020 — which was the lowest in history.
The U.S. has saved millions of adoptable pets from being euthanized by moving them from states with too many, to states that need more
Good news for dogs: While there isn’t a shortage of adoptable dogs in the U.S., there is a difference in where they are adopted most. States like Mississippi have too many, but Massachusetts needs more.
The “animal relocation” movement isn’t just helping pets find homes, it’s helping euthanasia rates plummet, and helping build capacity to help all kinds of animals.

Since June 2020, Denver has been dispatching mental health teams on certain 911 calls – the program is so successful, they’re expanding it again
In June 2020, Denver announced its Support Team Assisted Response (STAR) program, which dispatches licensed mental health professionals instead of police for certain 911 calls. In its first year, the program was so successful, the city expanded it to include more vans and more response teams.
Now, the Denver City Council has unanimously approved $1.4 million to expand the STAR program again — from 3 vans to hopefully 6 teams and 10 total response teams.
Since it launched, local CBS News affiliate reports the STAR program has responded to over 2,700 calls [as of March 2022]. The program dispatches a mental health clinician with a paramedic or EMT for each call they respond to.
The world surpassed 1 terawatt of installed solar energy capacity
The world passed a major renewable energy milestone: There are now enough solar panels installed throughout the world to generate 1 terawatt (TW) of electricity from the sun, according to the latest estimates.
That's enough to meet the electricity demands of nearly every country in Europe combined.
An estimated $60 billion in medical debt was removed from consumers’ credit reports
Good news for people with medical debt! The 3 major credit reporting agencies — Equifax, Experian and TransUnion — announced that, beginning this summer they will implement three changes that will remove roughly 70% of medical collection debt from Americans' credit reports.
First, as of July 1, all paid medical debt will no longer be included on reports — previously, any debt that went to collection would be included for 7 years, even if it had eventually been paid.
Beginning early [2023], no medical debt under $500 will appear on a report at all. This one is especially good news because recent data from the Consumer Financial Protection Bureau (CFPB) showed the majority of medical debt is under $500.

A new report found that if the current pace of wind and solar growth continues, the world will meet its climate targets
A new report from independent climate think tank Ember found that if the current pace of wind and solar power capacity growth continues through 2030, the world is on track to limit global warming to 1.5 degrees Celsius.
While some impacts are already unavoidable, the 1.5-degree target is what climate experts say warming needs to be limited to avoid many of the worst impacts of climate change globally. So this is really good news.
A team of engineers at Stanford announced they've developed a solar cell for solar panels that can generate electricity at night, too.
Standard solar panels can provide electricity while the sun is up during the day, and while installing a battery can help store electricity for use when the sun is down, panels that can generate electricity at night is even more efficient and sustainable.
As NPR reports, the solar cell uses a thermoelectric generator, which can pull electricity from the small difference in temperature between the air outside and the solar cell itself.
A tech company is electrifying the world’s high-polluting scooters through networks of swappable batteries
Taiwan-based tech company Gogoro is helping electrify the hundreds of millions of high-polluting two-wheelers around the world through networks of swappable batteries.
And it's a good thing, too: you might be surprised to learn how many people drive them — and how polluting they are. China, India, and Indonesia alone have more than 500 million two-wheelers, and globally, "over 50% of all commute miles done every day is actually done on two wheels," Gogoro CEO Horace Luke told the Volts podcast.

For the first time ever, renewable sources met 100% of its electricity demand in California
For the first time ever, renewable electricity sources met 100% of California's energy demands. As the Desert Sun reports, on Saturday, April 30 at 2:45 p.m., energy demand statewide hit 18,672 megawatts.
Of that demand, 101% of the power provided came from renewables, according to a continuous tracker provided by California Independent System Operator (CAISO) a nonprofit that oversees the state's bulk electric power system and transmission lines.
Two-thirds of the 18,000 megawatts were provided by solar power, and the rest came from wind, geothermal, and other renewable sources. The renewable electricity lasted almost 15 minutes before decreasing to about 97% renewables.
While it only lasted 15 minutes, it's an incredibly encouraging and exciting milestone as we work to decarbonize our electric grid — and proof of what we already knew: a carbon-free future is a realistic, viable goal.
In a medical breakthrough, scientists identified a blood marker in babies at higher risk of SIDS
According to the CDC, 1,248 infants died in 2019 due to SIDS (Sudden Infant Death Syndrome). While this number has steadily declined over the past two decades — from 130.27 per 100,000 live births in 1990 to 33.3 in 2019 — as preventative measures have been recommended by doctors and implemented by parents, any risk indicators or exact causes of SIDS have been unknown.
In a historic agreement, the U.S. men’s and women’s soccer teams will now be paid equally
It's a landmark victory for equality! US Soccer and the unions for both the US Soccer MNT and US Soccer WNT announced they reached a new agreement that will achieve "equal pay and set the global standard moving forward in international soccer."
June
A new report found sales of gas-powered cars are in ‘permanent decline’ and likely peaked in 2017
Good progress for the clean energy transition: A report by industry analysts at BloombergNEF found that sales of non-plug-in, internal combustion-powered vehicles peaked in 2017 and are now in "permanent decline."
While the report found that in 2025, traditional gas-powered vehicles will still make up the majority of car sales — that same year, 20.6 million plug-in vehicles will be sold globally. That's about triple the projected 6.6 million that will be sold in 2022.
Home to a bison range, the U.S. government returned 18,000 acres of undeveloped land in Montana to Native tribes
In the 1900s, 18,000 acres of undeveloped land in northwest Montana was taken by the U.S. Government without the consent of the Confederated Salish and Kootenai Tribes.
In 2020, Congress passed a law that would transition management of the land from the U.S. Fish and Wildlife Service back to the tribes, and in 2021, U.S. Interior Secretary Deb Haaland signed off on the law.
A ‘game-changer’ for disaster relief settings, solar microgrids are helping keep Ukraine’s hospitals running
In a conflict where power sources may be targeted, a solar microgrid has the additional advantage of being less detectable than a diesel generator, both because it's quieter and because it gives off less heat. It also negates the need to store large amounts of highly flammable fuel.
Creating thousands of jobs, the U.S. is plugging abandoned oil and gas wells leaking climate-warming methane
According to the U.S. Interior Department, there are tens of thousands of old oil and gas wells on federal lands nationwide, and at least another 130,000 on state and private lands.
And now, as reported by Thomson Reuters Foundation, for the first time, the government is giving the abandoned wells major attention in an effort to curb environmental pollution, reduce climate-heating emissions of methane, and create green jobs.
President Biden officially signed the first major gun safety legislation in nearly 3 decades into law.
As The New York Times reports, the bill enhances background checks for gun buyers between 18 and 21 years old, incentivizes states to implement “red flag” laws that enable firearms to be temporarily confiscated from people deemed dangerous, provides hundreds of millions of dollars for mental health and school safety, extends a federal law that prohibits domestic abusers from purchasing guns to dating partners (instead of just married partners), and more.
Are these measures enough to eliminate the threat of gun violence from all the places it need to be? Absolutely not. And yet, while we certainly wish there was a lot more included — without a doubt, these measures *will* save lives from gun violence. And that’s important progress worth celebrating.
July
The Suicide and Crisis Lifeline ‘988’ officially launched across the U.S.
The national Suicide and Crisis Lifeline "988" is now officially launched in the U.S. Starting today, July 16, anyone experiencing a mental health emergency can call or text the 3-digit number, 24/7, and be connected to a network of 200 local crisis centers and trained counselors.
Previously, those experiencing a mental health crisis had to dial a 1-800 number which could be difficult to remember or track down in the midst of an emergency — or 911, which was not set up to respond to mental health needs.
After nearly going extinct in the region, as many as 150 fin whales were seen feeding off the coast of Antarctica
In more whale good news: A new study published in Scientific Reports details the first scientifically documented observation of a large group of fin whales feeding off Elephant Island in Antarctica.
The incredible success story is credited to a 1982 decision by the International Whaling Commission to ban the practice of commercial whaling that had driven several species to the brink of extinction.
The number of independent bookstores is at its highest in years – with more diverse owners than ever
The American Booksellers Association (ABA), the trade group for independent bookstore owners, says it now has 2,010 members at 2,547 locations — 300 more than it had in Spring 2021, and the most members its had in years. That’s doubly significant because in 2020 the ABA also tightened its rules to only allow stores which “primarily sell books” (over 50 percent of inventory), as opposed to any stores offering books.
While the ABA credits the spike in members to owners that delayed their memberships during the pandemic, over 100 of them are stores that opened in the last year — dozens of them by non-white owners.
August
The Biden Administration announced it will plant 1 billion trees in the western U.S.
Good climate news! 🌳 A large-scale win for reforestation efforts, the Biden Administration announced its plans to plant over 1 billion new trees across millions of acres of burned and dead woodlands in the Western part of the U.S.
Ecologists and foresters are battling the increasing brunt of wildfires and insect infestations, leaving the government overwhelmed by the need to plant new trees, as forests struggle to naturally regenerate.
Hawaii got it’s last-ever shipment of coal – its last coal plant is closing in September
Good climate news! The Governor of Hawaii announced that the state received its last-ever shipment of coal — Hawaii's last remaining coal plant is shutting down in September.
This historic milestone is a part of Hawaii's 2014 pledge to get to 100% renewable energy by 2045 — becoming the first state to make a net zero pledge.
A new Lyme disease vaccine is now in the final phase of its clinical trial
Created by Pfizer and French drugmaker Valneva, a new vaccine for Lyme disease called VLA15 is now officially in its third and final phase of a human clinical study. If it's successful, the companies say they'll seek authorization for use in 2025 — while that's still a few years off, this is incredible progress to celebrate.
[Lyme disease is] estimated to impact around 476,000 people in the U.S. and 130,000 people in Europe every year — and the parts of the world where it spreads is growing, making the need for a vaccine even more important.
Congress passed the Inflation Reduction Act – it includes the largest federal investment ever in fighting climate change
It includes: extending incentives and tax credits for building clean energy capacity, providing financial incentives to consumers for purchasing electric vehicles and making efficiency and electrification upgrades at home, investments in environmental justice, and more.
It's the largest-ever investment in fighting climate change in the U.S. — around $370 billion total. And energy experts say the bill will cut emissions by about 40 percent below 2005 levels by 2030, both getting the Biden administration on track to meet its goal of cutting emissions in half by that year *and* getting the U.S. two-thirds of the way to its Paris Agreement goal.
In Burundi, former rival combatants are now working to rebuild forests destroyed by civil war
Burundi, one of the smallest countries in Africa, has just 6.6% of its original forests remaining, the legacy of a brutal civil war in which forests weren’t spared the violence inflicted by either side.
As Mongabay reports, the formerly warring factions are working together on a reforestation project launched by the country in 2018. It's been hailed as a fantastic initiative, with over 150 million trees planted already.
September
France became the first country in the world to ban fossil fuel advertisements
First proposed in 2019, France just implemented a ban on all advertisements promoting coal and oil, becoming the first country in the world to do so. Beginning in June 2023, the ban will include advertisements for natural gas, too. Companies who violate the ban will be fined $100,000 for each instance and could pay double for repeated violations.
Organizations around the world are rebuilding mangrove forests in coastal areas where they’ve been destroyed
For coastal communities like those in the Bahamas, mangroves mean stability and protection. They’re a safe harbor for hundreds of creatures. And they help protect communities from threats associated with climate change, including worsening storms, rising sea levels, and erosion.
They’re important for those living far from a coastline, too: Mangrove forests are an important tool in combatting climate change.
The world’s largest offshore wind farm is now fully operational – it will help power 1.4 million U.K. homes
A beautiful sight to see: The Hornsea 2, the largest offshore wind farm in the world is now operating at full capacity. Located off the east coast of England, it’s 165 turbines cover an area equal to more than half the size of New York City, and it help power more than 1.4 million homes in the U.K.
Patagonia founder Yvon Chouinard just donated the entire $3 billion company to fight climate change
"Earth is now our only shareholder." Patagonia founder Yvon Chouinard just announced he would be donating the entire company, worth about $3 billion, to a trust and a nonprofit organization fighting climate change. Any profits that they don’t reinvest in the company will go to fight climate change — which will be about $100 million per year.
October
North America’s first utility-scale renewable energy plant combining wind, solar, and storage opened in Oregon
We've seen clean energy with onsite storage before — but we’ve never seen it like this! A small town in Oregon just opened North America's first utility-scale "hybrid" wind-solar-battery renewable energy plant.
It has the capacity to power 100,000 homes and when operating at maximum capacity, can produce over half the power that was generated by Oregon’s last coal plant, which was demolished in August.
Since the facility can store energy onsite, it’s addressing a key challenge in the clean energy transition — not relying on fossil fuels to fill the energy demand when the wind isn’t blowing and the sun isn’t shining.
The FDA approved a new drug to treat ALS that was funded by money raised in the Ice Bucket Challenge
Back in 2014, your social media feed was likely filled with people doing the Ice Bucket Challenge to raise money to fight ALS, also known as Lou Gehrig's disease.
17 million people participated in the challenge, including celebrities, athletes, and politicians, and it raised over $115 million. A large portion of that money went to researching treatments for ALS — the first of which was just approved by the FDA.
While it's not a cure for the fatal neurodegenerative disease, it does slow down the progression of ALS and extends the life of those living with ALS.
President Biden pardoned thousands of people convicted of marijuana possession
Additionally, Biden said his administration would begin the process to review how marijuana is classified, because it "makes no sense" that it is currently classified at the same level as heroin, and more seriously than fentanyl.
The pardons will clear about 6,500 people who were convicted [under federal law, not state law] between 1992 and 2021 and thousands more who were convicted of possession in the District of Columbia.
The Gates Foundation just pledged $1.2 billion to eradicate polio globally
The money will go to the Global Polio Eradication Initiative's work specifically in Afghanistan and Pakistan — the last two countries where polio is endemic — through 2026. It will also be used to help stop new outbreaks of the virus.
November
After two years of deadly conflict, Ethiopia’s civil war agreed to stop fighting
After two years of conflict that has killed thousands, displaced millions, and resulted in famine for hundreds of thousands, the Ethiopian government and Tigray regional forces announced this week they've agreed to end hostilities “permanently.”
While analysts say the road to a comprehensive peace deal will be long, experts are celebrating the announcement for the significant diplomatic breakthrough that it is. And we are too!
John and Hank Green’s fundraising campaigns are helping build a maternal health hospital in Sierra Leone
Since 2019, Hank and John Green, along with their fanbase, have been committed to raising at least $25,000,000 to support the construction, staffing, and supplying of a new maternal health hospital in the Kono District of Sierra Leone.
Farmers started an ‘open source’ seed initiative to combat monopolies and improve biodiversity
Most farmers don’t own the seeds they sow on their fields — they rent them. A few companies have a monopoly on the global seed trade, and breed “cash crops” like corn and soy — with profits as the priority, not biodiversity, world hunger, or small farmers.
To combat that destructive model, in 2012 a handful of agriculture experts founded the Open Source Seed Initiative (OSSI) as an alternative to the monopolies. The model is similar to open source software — someone develops the seeds, and offers the resource for everybody to share.
About 50 seed breeders have already signed on with OSSI in the US to offer nearly 500 seed varieties, and other open source seed organizations are popping up in Europe, Argentina, India and more.
Using transparent solar cells, Swiss scientists developed windows that can generate electricity
Get lots of natural light while generating electricity? Scientists in Switzerland are making it possible with transparent solar cells that can be used to make electricity-gener ating windows — and they just reached a new efficiency record, too.
The low-cost dye-sensitized solar cells use photosensitized dye on a semiconductor surface that converts visible light into energy.
December had plenty of good things happen too! However, it goodgoodgood stopped updating their running list to do more roundups so close to the end of the year. Luckily, my blog has plenty of articles about good things that happened in December for you to review!
Although the advantages of wind energy like environmentally friendly, reducing the dependence on traditional energy sources, and opening open door for more job creation, it has also several disadvantages.
