Abstract

Abstract: From the determination of the flat-band potentials of the n-CdSe anodes in various polysul-fide solutions, the adsorption of OH^-ions on the anodes under different conditions and the preferential adsorption of sulfide ions in S^-, S^2-, OH^-electrolytic solutions are clarified. The charge transfer mechanism at the interface of n-CdSe in the pojysulfide solution is elucidated with the help of rotating ring-disk electrode measurements.

Key words: Photoelectrochemistry, Charge transfer, n-CdSe/polysulfide solution interface
