Thin film cadmium selenide has been prepared by a new electrochemical process in which the film is deposited at the cathode from a nonaqueous solution containing tri-n-butylphosphine selenide as the selenium source. The films are found to be less dense than those prepared using selenosulfite ion. The as-deposited films appear free of cracks and pinholes when deposited on titanium, but cracks develop when the films are annealed. A stoichiometric composition is obtained for the film over a 0.4V potential range. Power conversion efficiencies for films prepared under a variety of conditions range from 1.0 to 4.2% for surface areas ca. 1.0 cm/sup 2/. The presence of large concentrations of chloride ion in the deposition solution seems to have little effect on the composition or photoresponse of the film. Diethylene glycol appears to be a better solvent than propylene carbonate for this deposition process.
