SnS薄膜的两步法制备及其光电性能研究
Research on the Optoelectronic Properties of SnS Thin Films Prepared by Two-Stage Process
摘要
Abstract
SnS thin films were prepared by two-stage process. Sn precursor layers were deposited on glass substrates by sputtering and followed by sulfurization of the metallic tin precursor layers at 220 ℃ in a furnace for 60 min. The characterization results of microstructures, composition and optical and electrical properties show that the SnS film presents p-type conductivity and has a (040) preferred grain orientation; SnS film has an orthorhombic structure, and the surface is uniform and density with the ratio of Sn to S close to 1. It is found that the film shows a high optical absorption coefficient of 5 ×104 cm-1 and persistent photoconductivity effect. It has a direct energy band gap of 1. 23 eV. The prepared SnS film is useful as an absorption layer of solar cells and for fabrication of photo-sensitive device.关键词
