The photoelectrochemical behavior of n-CuIn/sub 5/S/sub 8/ a chalcogenide having a spinel-type structure, has been studied in various electrolytes by measuring the spectral response, the current-potential characteristics, an the differential capacitance. The best results have been obtained in an aqueous sulfide-polysulfide solution, where the CuIn/sub 5/S/sub 8/ semiconductor electrode shows an excellent stability. The flatband potential of this semiconductor electrode has been found to depend on the solution composition. The most negative values have been observed in the sulfide-polysulfide solution, owing to specific adsorption of S/sup 2 -/ ions on the electrode surface. Preliminary results on the output power characteristic of the CuIn/sub 5/S/sub 8/ photoelectrochemical cell are also discussed.
