· RbCu(SbS2)2

RbCu(SbS₂)₂ is a ternary chalcogenide semiconductor compound combining rubidium, copper, and antimony sulfide units in a layered crystal structure. This material is primarily of research interest for optoelectronic and thermoelectric applications, belonging to a family of quaternary sulfides being explored as alternatives to conventional semiconductors for photovoltaic absorbers and solid-state thermal-to-electric conversion. While not yet commercialized at scale, chalcogenide semiconductors like this compound are investigated for their tunable bandgap, potential low toxicity compared to lead-halide perovskites, and earth-abundant elemental composition.
