Antimony triselenide (Sb2Se3) is one of the most promising absorber material choices among the inorganic semiconductors that has attracted much attention today. However, highest recorded efciencies for Sb2Se3 solar cells are still lower than ideal. Exploring antimony selenosulfde (Sb2(SxSe1−x)3) to increase device performance is one option because some features of alloyed Sb2(SxSe1−x)3 depend on composition such as bandgap and band position. In this study, two-step process was used to grow Sb2(SxSe1−x)3 thin flms. In the frst stage, Sb2Se3 thin flms were deposited on soda lime glass substrates using direct current magnetron sputtering technique. In the second stage, Sb2Se3 thin flms were exposed to sulfurization process in a quartz ampoule to obtain Sb2(SxSe1−x)3 thin flms. Characterization results showed that morphological, optical, and structural properties of Sb2(SxSe1−x)3 thin flms grown by presented method were highly dependent on amount of sulfur in the flms. By the adjustment of the S/S+Se atomic ratio, Sb2(SxSe1−x)3 absorber materials with suitable bandgap, favorable orientation and compact morphology can be obtained for photovoltaic applications.
