作者描述了在硒和硒化物之间的界面处，导致Se形成的化学反应和Se作为多硒化物的电化学还原之间的竞争方面的恒电流电沉积CdSe的机制。该机制导致所得膜的花椰菜形态。这种形态对于液体结太阳能电池配置中的光电阳极是理想的，并且作者描述了这种电极的性能。尽管独特的形态，固态性能的薄膜可以进行评估，这些评估的方法。液体结太阳能电池的性能受到暗电流和材料介电性质的限制。作者还描述了金属离子如Zn/sup +2/、Ru/sup +3/和Ga/sup +3/对各种电极性能的影响。
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.
