ABSTRACT:
A photovoltaic cell is formed by combining a spray process, forming a crystalline layer containing cadmium and sulfur, and an evaporation process, depositing copper chloride for converting to Cu.sub.x S. The crystals containing cadmium and sulfur are heated in an atmosphere of cadmium and chlorides to obtain crystals having at least one dimension greater than 0.5 micron and a planar layer of Cu.sub.x S is formed on the large crystals. A layer of Cu.sub.x S having a thickness of 0.5-1.0 micron is obtained. Electrodes are formed from evaporated gold or chromium or a metallic paste including silver or copper. Zn.sub.x Cd.sub.1-x S may be substituted for CdS through at least part of the crystalline layer for improved Voc.
