Semiconductor manufacturing technique holds promise for solar energy

Monday, May 24, 2010 - 10:22 in Physics & Chemistry

Thanks to a new semiconductor manufacturing method, the future of solar energy just got brighter. Researchers have developed a more efficient, lower-cost method of manufacturing compound semiconductors such as gallium arsenide for many electronic device applications, including solar cells. The group deposits multiple layers of the material on a single wafer, creating a layered stack of gallium arsenide thin films, then transfers one layer at a time to another substrate -- glass, plastic or silicon.
