Research on electrochemical photovoltaic cells incorporating thin film CdSe and CdSe/sub x/Te/sub 1-x/ photoanodes has progressed to the point where efficiencies of up to 7% can be achieved on small area electrodes using a polysulfide electrolyte. Higher efficiencies can be obtained in alternate electrolytes in significantly less stable systems. The major limitations on cell efficiency are associated with the open circuit voltage and fill factor. At present, the most promising photoelectrochemical storage system is an in situ three electrode cell under investigation at the Weizmann Institute and consists of an n-CdSe/sub x/Te/sub 1-x/ photoanode and CoS counterelectrode in a sulfide/polysulfide electrolyte and a Sn/SnS storage electrode isolated in an aqueous sulfide electrolyte.
