Peak Energy: Efficient Thin-Film Solar Cells - 0 views

Energy Net on 06 Dec 08The thin film solar field is still a hot bed of activity - Technology Review has a post on a prototype cell that uses photonic crystals - Efficient Thin-Film Solar Cells. Researchers at MIT have unveiled a new type of silicon solar cell that could be much more efficient and cost less than currently used solar cells. Materials science and engineering professor Lionel Kimerling and his colleagues presented results of the first device prototype at a recent meeting of the Materials Research Society in Boston. The design combines a highly effective reflector on the back of a solar cell with an antireflective coating on the front. This helps trap red and near-infrared light, which can be used to make electricity, in the silicon. The research team is licensing similar technology to StarSolar, a startup in Cambridge, MA.
