n-CuInSe2, n-CuInS2 and n-CuIn5S8 were used as photoanodes in electrochemical photovoltaic solar cells, using aqueous polysulfide electrolyte. CuIn5S8 was found to be less stable than CuInS2. Because of kinetic limitations of polysulfide-based systems, the CuInSe2/aqueous polyiodide cell was studied and optimized to yield stable, near 12% AM1 conversion efficiency. The strategy used to achieve this is described. (Photo)electrochemical methods were used to characterize the semiconductor materials and a photoelectrochemical test was developed to gauge the photovoltaic activity of p-CuInSe2 layers used in solid state cells. Solid-state chemical studies on the (Cu2X)2-(In2X3)(X=S,Se) system, and the use of photoelectrochemistry in them, are briefly described.
