Book excerpt: Research on electrochemical photovoltaic cells incorporating thin film n-CdSe and n-CdSe(subscript 1-x)Te(subscript x) photoanodes has resulted in efficiencies up to 7.5 percent using small area electrodes in polysulfide electrolytes. Efficiencies close to 10 percent can be achieved using alternate electrolytes in significantly less stable systems. The major limitations on the efficiency of II-VI photoelectrochemical cells are associated with the open circuit voltage and the fill factor. Research on CuInSe(subscript 2) electrochemical photovoltaic cells has resulted in efficiencies up to 11.7 percent using single crystal n-CuInSe(subscript 2) photoanodes in aqueous electrolytes. The n-CuInSe (subscript 2) surface and the electrolyte have been optimized to produce a highly stable semiconductor/electrolyte junction. A review will also be given on the status of photoelectrochemical storage cell research. In situ photoelectrochemical measurement techniques have been used to probe the semiconductor/electrolyte interface and have been used to support the characterization of semiconductor materials for solid state photovoltaic applications.
