通过用Zn++离子处理表面，光电化学太阳能电池用n-CdSe薄膜电极的开路电压、填充因子和功率转换效率得到了提高。这些电极的总效率从1.5%提高到高达6.5%，在1 M ZnCl 2中浸泡处理。光电化学测量和俄歇光谱表明，所观察到的改善是由于锌掺入到CdSe薄膜的表面区域中而导致平带电位向更负的值偏移的结果。
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++ ions. The overall efficiency of these electrodes was increased from ∼5% to as high as 6.5% with a soaking treatment in 1 M ZnC12. 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.
