Turn your windows into solar panels: an energy revolution is underway thanks to a scientific breakthrough from Oxford. How far could this in
Researchers at the University of Oxford have just reached a major milestone that could redefine our domestic energy sources. By integrating photovoltaic technology into our windows, they open the doors to a daily and widespread use of solar energy.
At the heart of this innovation is perovskite, a synthetic material known for its ability to efficiently capture light. Unlike traditional silicon solar panels, these perovskite cells are distinguished by their incredibly thin thickness, a feature that facilitates their application on various surfaces.
The researchers have developed a layer stacking process designed to capture a broader light spectrum. This allows for a certified energy efficiency of 27%, an impressive figure validated by the National Institute of Advanced Industrial Science and Technology (AIST) in Japan. Indeed, this performance rivals the best silicon panels available on the market.
Mineral Cup Round 1: Perovskite vs Copper
An old favorite goes up against our first elemental mineral of the year!
https://www.mineralcup.org/2024/vote/r1m03
PEROVSKITE
This previous finalist is rare in pop culture but a heavyweight in geology (and not just because it makes up Earth's deepest mantle).
Name: After some guy.
Bling: Delightfully cubic!
Uses: Members of the perovskite family can make very efficient, flexible solar panels.
Team Lick? Some are toxic, and classic perovskite (calcium titanate) powder can cause skin and respiratory irritation. I'd hold off.

COPPER
One of the only non-silver metals, copper boasts a long and storied history with humanity.
Name: After Cyprus, the Romans' principal source of copper.
Bling: From unique red-orange sheen to distinctive green oxidation, elemental copper shines aesthetically! And if you like the appearance of competitor turquoise, you have copper to thank.
Uses: We've been using copper for at least 10,000 years! Nowadays we use copper in electronics, buildings, and many useful alloys and salts.
Team Lick! Not only safe to lick with a delicious bloody taste, humans need copper as a trace mineral in our diet.

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?

Australian researchers show next gen solar cells can beat the heat
Good News Notes: “Australian researchers have demonstrated that new solar panel designs and manufacturing techniques have the potential to solve some of the key challenges of operating in high temperatures, showing that they not only produce more useful electricity but have longer operational lives thanks to their ability to beat the heat. In new research published in the journal Progress in…

Catching Rays
X-rays painlessly zip through flesh and tissue, revealing fractures or cracks in bones in the patterns left on a detector. While they’ve revolutionised modern medicine, X-rays also carry risks – frequent exposure to high 'doses' may cause disease. So radiographers are on the lookout for ways to reduce our exposure to X-rays. Bringing together several novel technologies, here a new 3D printing technique sprays an aerosol mixture of perovskite, a mineral which helps to catch X-rays, into a pattern of pillars studded onto a supporting layer of graphene. The tiny bed of sensitive squares forms a cheap and highly-sensitive X-ray detector, each contributing pixels to a computer image with 1000 times lower doses of X-rays than often used today. This new device also requires less expensive machinery, potentially promising safer medical imaging available across the world.

Scientists are now using help from artificial intelligence to discover the best recipe for perovskite solar cell technology.
"Perovskites have been a hot research topic for the past 10 years, but we think we really have something here that can move us forward."
The so-called “perovskite solar cells” (PSCs) can turn sunlight into energy, just like regular silicon-based solar panels. Scientists came up with the idea over a decade ago — but until now, they’ve struggled to come up with a cost- and energy-efficient recipe.
