Researchers developed a solar collector with a dielectric Bragg mirror, optimizing energy conversion by separating sunlight ...

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 ...

Consumer interest in rooftop solar is higher than ever. The most recent numbers from Pew Research show 89% of U.S. adults favor the expanded use of solar power, while only 9% oppose. Historically, ...

(Nanowerk News) The sunlight received by Earth is a mixed bag of wavelengths ranging from ultraviolet to visible to infrared. Each wavelength carries inherent energy that, if effectively harnessed, ...

Scientists in Poland have measured the effect of solar radiation spectra in variable weather conditions on the performance of different kinds of PV module technologies. They found that amorphous ...

Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). Different colors have different energies, and no single semiconductor has a ...

This work, which verifies one of the predictions of Einstein's General Relativity, is to be published in the journal Astronomy & Astrophysics. The General Theory of Relativity, published by Albert ...

After four centuries of advances, astronomers now capture the Sun’s swirling, dynamic features in stunning detail.
