摘　　要：以硫代乙酰胺、三乙醇胺、氯化亚锡和氨水作反应物,氯化铵作缓冲剂,采用化学浴法在玻璃衬底上沉积SnS薄膜,并用X射线衍射(XRD)、扫描电子显微镜(SEM)等分析手段对样品进行了表征。XRD分析结果表明样品为斜方晶体结构的多晶SnS薄膜。SEM观察结果显示薄膜表面呈竹叶状多孔形貌,此结构有利于增加太阳电池的光吸收。SnS thin films were deposited on glass by the chemical bath deposition method using triethanolamine (TEA), thioacetamide, SnCl2·H2O, ammonia (aqeous) as reactants and NH4Cl (aqeous) as buffer aqeous. The specimens were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The XRD results suggested that the specimens were polycrystalline SnS thin films with orthorhombic structure unit. And SEM results indicated that the films surface took on the bamboo leaf-shaped morphology, and the porous structures were favorable for the solar cell.
