Research on electrochemical photovoltaic cells. Final report, 1 July 1982-30 April 1983
This report contains results of research conducted to provide a basis for designing a practical electrochemical solar cell based on the II-VI compound semiconductors. Emphasis was on developing new solvent/redox systems and conducting films that will stabilize the II-VI compounds against photodissolution without seriously degrading the long-term solar response and on applying electrochemical photocapacitance spectroscopy (EPS) to the development of improved thin-film materials. In photoelectrode stabilization, work focused on electrodeposited polypyrrole to determine the effects of the deposition parameters on the film density and electrical conductivity. These film properties were found to vary dramatically with the substrate, deposition conditions, electrolyte and anion employed, indicating there is considerable leeway for improvement. The most dense and highly conductive films have involved polymeric anions, nonaqueous solvents, and metallic substrates. A promising approach to providing an improved surface for polymer deposition on semiconductors has been identified. In the EPS area, the focus was on the development of thin-film CdSe materials.
