摘要： 本文探讨了单晶n-CdTe在水溶液中的稳定性和光致钝化行为,采用近代表面分析手段考察了电极表面形貌和组成的变化.通过选择适当的氧论还原偶及浓度配比,进行电极表面修饰,显著改善n-CdTe光电化学电池的稳定性.

Abstract: The stability of single crystal n-CdTe in aqueous solution and the photopassivation behaviour have been investigated. The changes of the surface composition and shape are examined by means of the solid surface analyses. The stability of n-CdTe photoelectrochemical cell is apparently improved by selecting the suitable redox couple or modifying the photoelectrode surface.
