Researchers at the Hebrew University of Jerusalem have created semi-transparent, color-tunable solar cells. Interestingly, ...

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 ...

Japan is pushing solar hydrogen into a new phase by teaching its materials to drink in colors of sunlight that used to go to waste. Instead of relying only on the most energetic visible wavelengths, ...
