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. The first quarter of the program (May 1, 1979 through August 1, 1979) is described. The emphasis to date has been to produce Cu/sub 2-x/Se films of good uniformity and reproducibility. The films are deposited onto glass substrates heated to approximately 200/sup 0/C. The Cu and Se are evaporated from separate sources, each individually monitored for rate by quartz crystal microbalances. The techniques used are readily adaptable for scale up to large volume production. Preliminary measurements of optical absorption, electron diffraction, and Hall measurements have been made.
