摘要
用化学浴沉积法制备了CdS薄膜 ,并研究了加超声波对CdS薄膜生长过程的影响。利用卢瑟福背散射 ,X 射线粉末衍射和扫描电子显微镜对薄膜的厚度、晶相和表面形貌进行了表征。结果表明施加超声波的作用能有效地改善薄膜的质量 ,制备出均匀、致密的有较好的晶体结构CdS薄膜。同时 ,通过时间的控制可以精确地控制薄膜在 5 0nm左右 ,以满足制备太阳能电池的特殊要求。
Ultrasonic agitation was applied during the chemical bath deposition of CdS thin films and a great difference in the growth of CdS thin films was found to be caused by ultrasonication. The thickness of the thin films was measured by Rutherford back-scattering (RBS) and the crystalloid structure was analyzed by X-ray diffraction (XRD). SEM was used to observe the surface morphology of the thin films. The results showed that ultrasonication can effectively improve the quality of the CdS thin films and the films preparated by this method were uniform, compact and well constructed. There were virtually no colloidal particles adsorbed on the surface. X-ray diffraction showed that the preferred orientation changed from hexagonal(002) /cubic( 111) to hexagonal(101). At the same time controlling the time of deposition could control the thickness of the films accurately to about 50 nm, which can meet the special need in preparation of thin film solar cells.
