A brightly (multi)colored future for electrochromic devices shines ahead

Vivid displays, enriched color variations and boosted stability are something everyone can look forward to encountering as advances are made in the electrochromic device (ECD) field Electrochromic devices (ECDs) are useful in controlling optical properties such as reflection and absorption and are particularly pertinent when it comes to use in smart windows, rearview mirrors and adaptive camouflage. Unfortunately, the widely used electrochromic materials show a lackluster display with minimal color changes and poor cycling stability, often only transforming between transparency and a single color with sluggish switching speeds. This study demonstrates the use of a more compatible component in the form of a highly porous tin oxide (SnO2) nanosheet scaffold, which provides better cycling, more color variations and a seamless performance than what the current technology has to offer. Researchers published their work in Nano Research.

Smart window material blocks rays without blocking views

An international research team led by scientists from Nanyang Technological University, Singapore (NTU Singapore) has invented a 'smart' window material that controls heat transmission without blocking views, which could help cut the energy required to cool and heat buildings.

Developed by NTU researchers, the new energy-saving material for electrochromic (EC) windows that operates at the flick of a switch is designed to block infrared radiation—which is the major component of sunlight that emits heat.

The new material has a specifically designed nanostructure and comprises advanced materials like titanium dioxide (TiO2), tungsten trioxide (WO3), neodymium-Niobium (Nd-Nb), and tin (IV) oxide (SnO2). The composite material is intended to be coated onto glass window panels, and when activated by electricity, users would be able to 'switch on and off' the infrared radiation transmission through the window.

The invention, which featured alongside the front cover of the journal ACS Omega, could block up to 70 percent of infrared radiation according to experimental simulations without compromising views through the window since it allows up to 90 percent of visible light to pass through.

Spray-on clear coatings for cheaper smart windows

New transparent spray-on coatings are conductive, cost-effective and rival the performance of current industry standards

A simple method for making clear coatings that can block heat and conduct electricity could radically cut the cost of energy-saving smart windows and heat-repelling glass.

The spray-on coatings developed by researchers at RMIT University in Melbourne, Australia, are ultra-thin, cost-effective and rival the performance of current industry standards for transparent electrodes.

Combining the best properties of glass and metals in a single component, a transparent electrode is a highly conductive clear coating that allows visible light through.

The coatings -- key components of technologies including smart windows, touchscreen displays, LED lighting and solar panels -- are currently made through time-consuming processes that rely on expensive raw materials.

The new spray-on method is fast, scalable and based on cheaper materials that are readily available.

The method could simplify the fabrication of smart windows, which can be both energy-saving and dimmable, as well as low-emissivity glass, where a conventional glass panel is coated with a special layer to minimise ultraviolet and infrared light.
