Efficient Thin-Film Solar Cells
December 4, 2008 | Source: Technology Review
MIT researchers have unveiled a new type of silicon solar cell that could be 15% more efficient and cost less than currently used solar cells.
It 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.
