Electrochemical photovoltaic cells (EPC's) have been characterized based on n-GaAs and propylene carbonate electrolytes. Photovoltages are limited to approximately 0.7 v due to electrode corrosion and lack of specific adsorption by the redox systems studied. Polarization of photo and counterelectrodes, resulting from low redox solubilities and electrolyte conductivities, are responsible for lower fill factors and short-circuit photocurrents for nonaqueous compared to aqueous EPC's. Potentially, these losses can be offset by higher voltages and long-term stabilities, particularly if specifically adsorbing redox couples can be found. 17 refs.
