Abstract:

This report summarizes preliminary investigations on photoelectrical systems involving thionine dye and inorganic reducing agents these systems offer potential for use as photogalvanic cells in solar energy conversion. The report stresses the thionine-cobaltIIethylene-diaminetetraacetate EDTA system, which has yielded voltages and currents comparable to and in some cases exceeding those which have been reported for the thionine-Fe2 system. Measurements on the thionine-CoEDTA2- system have been carried out using two types of transparent electrode, tin dioxide and goldpalladium. Effects of concentration and aging on voltages are reported here, as well as results of closed-circuit measurements under load.
