The purpose of this program is to investigate the feasibility of using Cu/sub 2-x/Se as a semiconductor material for the low cost production of photovoltaic solar cells. Progress is reported. The Cu/sub 2-x/Se films are produced by coevaporation from individually monitored Cu and Se vapor sources. With a substrate temperature of 170/sup 0/C, single phase cubic Cu/sub 2-x/Se films have been produced. These films have a direct band gap of 2.2 eV and an indirect band gap of 1.4 eV.
