Abstract
Improvements in large area, bifacially contacted silicon concentrator solar cells are reported. By combining prismatic covers which steer incoming light away from top contacts with improved low-resistivity cell processing, efficiencies above 25% were achieved for 1.6 cm/sup 2/ cells for concentration levels up to 200 suns. Several hundred cells of this type have been supplied to Sandia National Laboratories for incorporation into the next generation of high-performance silicon concentrator modules, which are expected to reach a module efficiency of 20%.Keywords
