The open circuit voltage, fill factor, and power conversion efficiency of n-CdSe thin-film electrodes for photoelectrochemical solar cells have been improved by treating the surface with Zn/sup + +/ ions. The overall efficiency of these electrodes was increased from approx.5% to as high as 6.5% with a soaking treatment in 1 M ZnC1/sub 2/. Photoelectrochemical measurement and Auger spectroscopy indicated the observed improvements were the result of a shift in the flat-band potential to more negative values due to the incorporation of zinc into the surface region of the CdSe thin film.
