The authors describe the mechanisms for galvanostatic electrodeposition of CdSe in terms of competition between chemical reactions that lead to Se formation and electrochemical reduction of Se as polyselenide, at the interfaces between selenium and selenide. This mechanism leads to a cauliflower morphology for the resulting film. This morphology is ideal for a photoanode in the liquid junction solar cell configuration, and the authors describe the performance of such an electrode. In spite of the unique morphology, solid-state properties of the film can be evaluated and the methodology for these evaluations is presented. The performance of the liquid junction solar cells is limited by the dark current and the dielectric properties of the material. The authors also describe the effects of metal ions such as Zn/sup +2/, Ru/sup +3/, and Ga/sup +3/ on the various electrode properties.
