NREL-Led Research Effort Creates New Alloys, Phase Diagram

A multi-institutional team led by the U.S. Department of Energy”s National Renewable Energy Laboratory (NREL) discovered a way to create new alloys that could form the basis of next-generation semiconductors. Semiconductor alloys already exist-often made from a combination of materials with similar atomic arrangements-but until now researchers believed it was unrealistic to make alloys of

NREL Researchers Capture Excess Photon Energy to Produce Solar Fuels

Scientists at the U.S. Department of Energy”s National Renewable Energy Laboratory (NREL) have developed a proof-of-principle photoelectrochemical cell capable of capturing excess photon energy normally lost to generating heat. Using quantum dots (QD) and a process called Multiple Exciton Generation (MEG), the NREL researchers were able to push the peak external quantum efficiency for hydrogen
