Electrophoretically Deposited CdS and CdSe Anodes for Photoelectrochemical Cells

The electrophoretic deposition of CdS, CdSe, and their mixtures has been studied for the preparation of thin film anodes for photoelectrochemical cells. These films were obtained in a homogeneous state on SnO/sub 2//sup -/ coated glass substrates from the suspensions using polar organic dispersion media. Prior to photoelectrochemical experiments, the thin film anodes were thermally treated for 3 hr at 400/sup 0/-600/sup 0/C. An energy conversion efficiency of 2% was observed for the photoelectrochemical cells using these film anodes in S/sup 2 -//S /SUB lx/ /sup 2 -/ electrolytes.
