Credit: Sean Kelley/NIST A voltage is applied across the semiconductor. When a photon hits the detector, its absorbed energy kicks an electron off an atom in the semiconductor – the same photoelectric effect that generates electricity in solar panels. That loose electron is accelerated by the applied voltage and causes a sort of chain reaction in which large numbers of adjacent atoms release an “avalanche” of electrons just as a small added stress can prompt an entire mountain...

Monograin layer solar cell with 6.4% efficiency The lightweight and flexible cell was built by Estonian researchers with microcrystalline powders. The device is claimed to be the most efficient solar cell fabricated with a semiconductor compound known as Cu2CdGe(SxSe1-x)4.Scientists at Estonias Tallinn University of Technology (TalTech) have developed a monograin layer solar cell based on a semiconductor compound made of microcrystalline powders that is known under the chemical formula Cu2CdGe(...
