A single gold nanoparticle tends to absorb within a narrow band. Much of its strongest response sits in visible wavelengths. In the new work, the scientists packed many particles into a tight, crystal ...

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

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, ...

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 report that gold nanospheres, named supraballs, can absorb nearly all wavelengths in sunlight — including some ...

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 ...

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 ...

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 ...
