Cs2AgVS4
semiconductor· Cs2AgVS4
Cs₂AgVS₄ is an experimental quaternary chalcogenide semiconductor compound combining cesium, silver, vanadium, and sulfur. This material belongs to the family of mixed-metal sulfides and is primarily investigated in research settings for optoelectronic and photovoltaic applications due to its tunable bandgap and potential for non-linear optical properties. While not yet commercialized at scale, compounds in this family are of interest as alternatives to lead halide perovskites for solar cells and as candidates for infrared sensing and frequency conversion devices, where their layered crystal structure and heavy-metal-free composition offer environmental and performance advantages.
