Abstract

Abstract

Antimony selenosulfide, Sb₂(S,Se)₃, displays superior optoelectronic properties such as strong absorption coefficient and easily tunable bandgap in the range of 1.1～1.7 eV. In terms of practical photovoltaic applications, this semiconductor material is relatively non-toxic, low cost, earth abundant, and stable against moisture and air. Recent investigations have witnessed the rapid development with the power conversion efficiency overcoming the 10% bottleneck in Sb₂(S,Se)₃ solar cells, demonstrating great potential for further investigations. In this perspective, the structural, crystal and optical properties of Sb₂(S,Se)₃ are introduced first, and then notable developments are highlighted, primarily in the past three years, in Sb₂(S,Se)₃ solar cells with film deposition by solution based methods. Finally, some possible strategies are proposed with regard to efficiency improvement.
