Cs2ZnSn3Se8
semiconductor· Cs2ZnSn3Se8
Cs2ZnSn3Se8 is a quaternary chalcogenide semiconductor compound combining cesium, zinc, tin, and selenium in a layered crystal structure. This material is primarily a research compound being investigated for photovoltaic and optoelectronic applications due to its tunable bandgap and potential for stable perovskite-alternative solar cells. Its appeal lies in replacing lead-based perovskites with earth-abundant, less-toxic elements while maintaining favorable electronic properties for light absorption and charge transport.
