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 ...

Solar collectors and absorbers convert solar radiation into thermal energy, playing a crucial role in meeting global heating demands across various sectors.

Traditional solar cells harvest only a narrow sliver of the electromagnetic energy pouring down onto Earth, and that's one of the reasons it's been so challenging to get solar efficiency beyond 20-30 ...

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 ...

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 ...
