Electrochemical photovoltaic cells II-VI compound thin film electrodes. Annual report, June 1980-June 1981
This year's program has focused on developing stable, thin film II-VI compound electrodes with sunlight efficiencies of 10%, for use with aqueous polysulfide electrolyte in frontwall and backwall illuminated electrochemical photovoltaic cells. The main effort has been directed towards establishing the relationships among processing of the thin films, resultant electronic properties, and I-V performance in order to produce electrodes with maximum power conversion efficiency. The efficiency of n-CdSe electrodes deposited on titanium substrates has been improved from between 3 to 5% to 5.5% to 6.5% by refinement of the thin film processing parameters as well as electrode surface treatment with ZnCl/sub 2/ solution. The efficiency of n-CdSe electrodes deposited on tin oxide coated glass has been improved from between 3 to 4% to the range of 6 to 6.5% due to modifications of the electrode geometry dictated by a photon loss minimization, and to electrode etching treatment.
