Abstract

Abstract: The transient photocurrent behaviours of Au modified CdSe thin film electrodes were studied in polysulfide solution.The reaction rate constants of interfacial heterogeneous charge transfer K_F, surface charge recombination K_R and photocorrosion K_c were estimated.Combining with the surface analysis of XPS and SEM, the interfacial kinetic behaviours of Au modified CdSe thin film electrodes were analysed.

Key words: Chemical modification, interfacial charge transfer, surface charge recombination, photocorrosion
