Tin (Ⅱ) sulfide (SnS) is composed of elements that are inexpensive, non-toxic and abundant in the Earth's crust. It is a p-type semiconductor with a band gap energy of 1.3 eV. It is therefore a potential candidate for use as a solar cell absorber material. In this study, SnS thin films were prepared using a close-space sublimation (CSS) method. SnS thin films were grown on soda-lime glass (SLG) and Mo coated SLG,CdS coated FTO glass substrates by thermal sublimation in vacuum, using sources of SnS. The dependence of the structural and morphological properties of films deposited by CSS method on the source temperature was investigated.
