Cadmium sulfide/copper ternary heterojunction cell research. Final report, January 8, 1979-June 7, 1980
Dual source, Se and CuInSe/sub 2/, coevaporation and flash evaporation of stoichiometric CuInSe/sub 2/ powder were investigated to develop a process of fabricating large area CdS/CuInSe/sub 2/ heterojunction solar cells. CuInSe/sub 2/ was seen to decompose upon evaporation, producing layered films in the dual source system. Annealing of these films and alternative dual sources have been considered. Single phase p type films have been produced but no devices have been made from such films. Flash evaporation circumvents the decomposition problem, and if one bakes the powder to obtain a small Cu excess as well as getting a Se excess in the film, p type CuInSe/sub 2/ films can be obtained. A 1% efficient device of 6 cm/sup 2/ area was made using a flash evaporated CuInSe/sub 2/ film. Annealing studies and measurements of spatial uniformity of this device are reported.
