ＣｄＴｅ薄膜半导体电极通过电沉积法制备。电沉积溶液组成对ＣｄＴｅ薄膜组成和性能有较大影响，通过在电镀液中添加某些稀土离子，结合ＸＲＤ、ＴＥＭ、ＸＰＳ和光电Ｉ－Ｖ特性曲线进行分析研究，表明电沉积ＣｄＴｅ薄膜存在择优取向，经２５０℃热处理后，晶粒长大，镀液中添加Ｙ３＋、Ｌａ３＋、Ｃｅ３＋和Ｎｄ３＋后增大尤为明显，晶粒线性尺寸最大达２．５—３．０×１０－７ｍ左右，并伴有孪晶产生，可提高薄膜Ｃｄ／Ｔｅ比等，有利于提高ＣｄＴｅ光电性能。经测试，其光电转换效率可增大到２．６—３．３％。
CdTe thin film semiconductor electrodes are prepared by electrodeposition. The composition of electrodeposition solution has a significant influence on the composition and properties of CdTe thin films. The addition of some rare earth ions in the plating solution, combined with the XRD, TEM, XPS and photoelectric I-V characteristic curve analysis showed that CdTe thin film electrodeposited preferred Orientation, after heat treatment at 250 ℃, the grains grow up, the addition of Y3 +, La3 +, Ce3 + and Nd3 + in the bath increases more obviously. The maximum linear grain size reaches about 2.5-3.0 × 10-7m Accompanied by twins, can improve the film Cd / Te ratio, etc., is conducive to improving the photoelectric properties of CdTe. After testing, the photoelectric conversion efficiency can be increased to 2.6-3.3%.
