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.
