摘　　要：分别采用化学池沉积 ( CBD)和真空蒸发法 ,在三种衬底 (玻片、ITO玻片、Sn O2 玻片 )上沉积 Cd S薄膜 ,并利用扫描电镜 ( SEM)、透射光谱、X射线衍射 ( XRD)等方法对沉积膜进行了测试分析 ,同时阐述了两种不同方法下 CdCdS polycrystalline thin films are used as a heterojunction partner for CdTe in CdS/CdTe thin film solar cells. Recently, there has been an increasing interest in the study of transparent conducting oxide (TCO)/CdS/CdTe solar cells for large area applications. In the TCO/CdS/CdTe cell structure, the CdS layer requires high optical transmittance, high resistivity and thin thickness. In efficient solar cells, CdS films have been deposited by several techniques, such as spray pyrolysis, vacuum evaporation and precipitation from an aqueous solution. In this paper, CdS thin films made by chemical bath deposition and vacuum evaporation are presented. SEM and XRD show that the polycrystalline thin films are continuous, homogeneous and with high compactness. A reaction mechanism is given in brief also.
