Strategies beyond recycling to bolster circular economy for solar and battery...
28 Jun 2022 at 10:39am
In a new comprehensive literature review, researchers have discovered that alternatives to recycling may have untapped potential to build an effective circular economy for solar photovoltaic (PV) and battery technologies. These alternative strategies, such as reducing the use of virgin materials in manufacturing, reusing for new applications, and extending product life spans, may provide new paths to building sustainable product life cycles.
Thin-film photovoltaic technology combines efficiency and versatility
27 Jun 2022 at 7:02am
Stacking solar cells increases their efficiency. Researchers have now produced perovskite/CIS tandem solar cells with an efficiency of nearly 25 percent -- the highest value achieved thus far with this technology. Moreover, this combination of materials is light and versatile, making it possible to envision the use of these tandem solar cells in vehicles, portable equipment, and devices that can be folded or rolled up.
A rethink of the building blocks for solar panels could help mass production
27 Jun 2022 at 7:01am
An original approach to mass-producing low-cost solar cell foundation blocks could lead to the wide adoption of solar panels made from perovskite ink -- a 'miracle material' -- according to new research.
Once seen as fleeting, a new solar tech proves its lasting power
16 Jun 2022 at 11:27am
Researchers have developed the first perovskite solar cell with a commercially viable lifetime, marking a major milestone for an emerging class of renewable energy technology. The team projects their device can perform above industry standards for around 30 years, far more than the 20 years used as a threshold for viability for solar cells.

Solar beats nuclear at many potential settlement sites on Mars
27 Apr 2022 at 7:05am
While most missions to the moon and other planets rely upon solar power, scientists have assumed that any extended surface mission involving humans would require a more reliable source of energy: nuclear power. Improvements in photovoltaics are upending this calculus. A new study concludes that a solar power system would weigh less than a nuclear system, and would be sufficient to power a colony at sites over nearly half the surface.
Uncovering the secret of ternary polymer solar cell success
21 Apr 2022 at 11:16am
A research team has used electron spin resonance spectroscopy to investigate a polymer solar cell while in operation. Molecular level comparison of the PTzBT/PC61BM system with and without added ITIC allowed them to establish the mechanism for the improvements in stability and power conversion efficiency observed when ITIC is added. It is hoped that this insight will contribute to the commercial realization of cost-effective flexible polymer solar cells.
