MIT spin-off plans to manufacture cheap, efficient solar cells
Researchers from MIT have improved commercial solar cells that will soon be significantly cheaper and more efficient than those available today. Ely Sachs, a professor of mechanical engineering at MIT, predicts that by 2012 such solar cells will be comparable in price with coal, which is about $1 per watt.
1366 Technologies´ solar cells are made from multi-crystalline silicon - a material that is normally less efficient than top quality single-crystal cells, but significantly cheaper. However, with the improvements by Sach´s group, the multi-crystalline solar cells reach about the same efficiency as the single-crystal variety.
