Semiconductor Electrodes. 19. An Investigation of S/Se Substitution in Single Crystal CdSe and CdS Photoelectrodes by Electron Spectroscopy.

摘要

Photoelectron spectroscopy studies verify the occurrence of S/Se substitution in single crystal CdSe and CdS photoanodes when used in photoelectrochemical cells containing S2- or Se2- solutions. A possible mechanism of the S/Se exchange is discussed as well as its consequences on the electrode stability and the output parameters of the photoelectrochemical cells. (Author)
