doi:10.7517/j.issn.1674-0475.1990.02.113

Abstract

Abstract: Photodissolution behaviours of semiconductor CdSe_0.63Te_0.37 thin film electrodes were investigated by cyclic voltammetry.By measuring the I-V performances of cathodic reduction processes for the products of photodissolution in Imol/L KCl solution,the photocorrosion of CdSe_0.63Te_0.37 thin film electrodes in polysulfide and ferro-ferricyanide solutions was tested.Surface photoetching processes and effects of pH was also studied by this method.X-ray photoele-ctron spectroscopy was used to analyze the changes of thin film surface prior to and after photoetching.

Key words: Photodissolution, photocorrsion, photoetching, thin film electrode, cyclic voltammetry, X-ray photoelectron spectroscopy
