Abstract
A process for electrodepositing cadmium and selenium onto a material suitable for use as a photoelectrode in a photovoltaic cell. The plating electrolyte, in one embodiment, consists essentially of an acid citrate bath including hydrated citric acid, hydrated sodium citrate, hydrated cadmium chloride and selenious acid. The deposit may be subsequently heat treated.
