Method of making a CdS/Cu /SUB X/ S photovoltaic cell

Patent ·
OSTI ID:5320301
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 /SUP X/. 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/ 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 cop Zn /SUB x/ Cd/sub 1//sub -/ /SUB x/ S may be substituted for CdS through at least part of the crystalline layer of improved Voc.
