Gold supraballs absorb most sunlight, boosting thermoelectric output and pointing to simpler, high-efficiency solar coatings. (CREDIT: ACS Applied Materials & Interfaces / color modification from grey ...

Gold nanosphere supraballs absorb a bout 90% of sunlight across all wavelengths, nearly doubling energy capture and boosting power output 2.4x when applied to solar cells. This supraball (left) is ...

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) developed a translucent solar panel to allow certain light spectrums to pass through that are optimal for ...

The ASTM G173 Standard Spectral Distribution of Sunlight represents a standard, reference solar spectrum that is used for solar photovoltaics testing and calibration purposes. It was defined in the ...

A salt called guanidinium thiocyanate can improve the efficiency and stability of perovskite solar cells, a new class of semiconductor that could make solar power cheaper and more powerful, according ...

Sunlight carries more energy than most solar devices can catch. That gap matters as heat waves grow worse. It also matters as grids strain under rising demand. A team working at the KU R&D Center at ...
