我们使用基于金属前体物质的油硫化的新方法合成了 SnS:Bi 薄膜。通过光谱透射率和 X 射线衍射 (XRD) 测量对薄膜进行表征，以确定光学常数和结构特性。研究表明，SnS:Bi 薄膜倾向于以 SnS 和 Bi(2)S(3) 相的混合物形式生长。研究还发现SnS:Bi薄膜的吸收系数大于10(4)cm(-1)，能带隙范围为1.37至1.47eV，表明该化合物具有良好的性能，可作为薄膜太阳能电池的吸收层。 (C) 2008 Elsevier Ltd. 保留所有权利。
We have synthesized SnS:Bi thin films using a novel method based Oil sulphurization of the metallic precursors species. The films were characterized through spectral transmittance and X-ray diffraction (XRD) measurements to determine both, the optical constants and structural properties. The studies revealed that the SnS:Bi films tend to grow with a mixture of the SnS and Bi(2)S(3) phases. It was also found that the SnS:Bi films present ail absorption coefficient greater than 10(4) cm(-1) and ail energy band gap ranging From 1.37 to 1.47eV, indicating that thiS compound has good properties to perform as absorber layer in thin film solar cells.
