A single gold nanoparticle tends to absorb within a narrow band. Much of its strongest response sits in visible wavelengths.

Though the sun produces more energy than we would ever need on Earth, current ...

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 have engineered tiny gold nanospheres that can soak up almost the entire spectrum of solar energy, promising a ...

Perovskite-silicon hybrid solar cells, launching in 2026, promise 34% higher efficiency than traditional panels. This ...

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 ...
