CsCu(SbS2)2
semiconductor· CsCu(SbS2)2
CsCu(SbS₂)₂ is a ternary chalcogenide semiconductor compound combining cesium, copper, and antimony sulfide units in a layered crystal structure. This is a research-phase material primarily of interest for photovoltaic and thermoelectric applications where narrow bandgap semiconductors and high charge-carrier mobility are advantageous. The compound represents an emerging class of halide-free perovskite alternatives and sulfide-based semiconductors being explored to overcome stability and toxicity limitations of conventional photovoltaic absorbers.
