摘要 以化学浴沉积法在普通载玻片上沉积不同时间得到汽车PbS薄膜,分析了样品的结构、微观形貌、光学性能。结果表明:沉积时间对汽车PbS晶体的完善程度有很大的影响,扫描电镜结果显示汽车PbS薄膜具有颗粒状-四面体-立方-八面体的转变过程;随着沉积时间增加,纳米晶粒之间相互聚集,呈现相互镶嵌形貌;汽车PbS薄膜的表面粗糙度随着沉积时间增加而增加,所有的样品均显示较低的透射率,其禁带宽度Eg从0.53eV减小到0.39eV,为改善和提高纳米汽车PbS太阳能电池性能提供重要的参考。

Abstract: The automobile PbS thin films grown on glass substrates at various deposition times by CBD method,the structural,micro morphology and optical properties of films were investigated.The results showed that the deposition times had a great effect on the perfection degree of crystals,scanning electron microscopy (SEM) images showed the transition of granular-tetrahedron-cubic-octahedral.With the increasing of deposition time,the nano grain was gather together,which presented inset surface morphology.The surface roughness of films increased with deposition time.All the sample had a low transmission,the decrease in band gap values Eg from 0.53 to 0.39eV,which can provide important reference for improve and enhance the performance of nanometer automobile PbS solar cells.
Key words:  chemical bath deposition    automobile PbS thin film    micro morphology    optical property
