Recent progress in the research on using CuSbS₂ and its derivative CuPbSbS₃ as absorbers in case of photovoltaic...

Thin-film solar cells show considerable application potential as alternative photovoltaic technologies. Cuprous antimony chalcogen materials and their derivatives, represented as CuSbS₂ and CuPbSbS₃, respectively, exhibit the advantages of low cost, massive elemental abundance, stability, and good photoelectric properties, including a suitable bandgap and large optical absorption coefficient. These advantages demonstrate that they can be used as light absorbers in photovoltaic applications. In this study, we review the major properties, fabrication methods, and recent progress of the performance of the devices containing CuSbS₂ and CuPbSbS₃. Furthermore, the limitations and future development prospects with respect to the CuSbS₂ and CuPbSbS₃ solar cells are discussed.
