Russak, M A

A thin film compound semiconductor electrode comprising CdSe/sub 1//sub -/ /SUB x/ Te /SUB x/ (0x1) is deposited on a transparent conductive substrate. An electrolyte contacts the film to form a photoactive site. The semiconductor material has a narrow energy bandgap permitting high efficiency for light conversion. The film may be fabricated by: (1) co-evaporation of two II-VI group compounds with a common cation, or (2) evaporation of three elements, concurrently.
