The Sb2(S1-x, Sex)3 compound has received considerable attention in photovoltaic applications due to its physical properties and for containing abundant non-toxic elements. However, solar cells based on this material present low efficiencies. In this work, we review some of the physical properties reported for the semiconductors Sb2S3, Sb2Se3 and Sb2(S1-x, Sex)3, and the main techniques of film deposition of the Sb2(S1-x, Sex)3 ternary material along with the reported efficiencies. Finally, a brief review of the scarce theoretical analyses of the main properties of this semiconductor (refractive index, band-gap energy, absorption coefficient and recombination) is presented. This review remarks the need of more theoretical analyses and modeling to optimize and improve the fabrication processes of Sb2(S1-x, Sex)3 solar cells in order to reach better conversion efficiencies.
