Process for the preparation of thin films of cadmium sulfide and precursor solutions of cadmium ammonia thiocyanate complex useful therein

摘要

A process is provided for the preparation of thin films of cadmium sulfide by deposition of cadmium sulfide formed in the thermal decomposition of an aqueous solution of cadmium ammonia thiocyanate complex, useful particularly in the preparation of thin cadmium sulfide films on electrically-conductive substrates useful in photovoltaic cells, and on thermally-conductive substrates useful in solar energy absorbers, for energy conversion systems.
