Sb2S3
semiconductorAntimony trisulfide (Sb₂S₃) is a layered semiconductor compound belonging to the V–VI binary chalcogenide family, with a quasi-2D crystal structure that makes it amenable to exfoliation and thin-film device fabrication. It is primarily investigated for photovoltaic applications—particularly as a light-absorber layer in next-generation thin-film solar cells—and emerging optoelectronic devices including photodetectors and thermoelectric modules, where its direct bandgap and favorable absorption coefficients offer advantages over conventional silicon in niche high-efficiency or specialized spectral-response applications. While not yet as mature as conventional photovoltaic materials, Sb₂S₃ represents a cost-effective, lead-free alternative in perovskite-inspired solar research and is gaining attention in the materials science community for its potential in flexible and tandem solar cell architectures.
