Cs2Cd2Bi2S5
semiconductor· Cs2Cd2Bi2S5
Cs2Cd2Bi2S5 is a mixed-metal sulfide semiconductor compound belonging to the family of quaternary chalcogenides, combining cesium, cadmium, bismuth, and sulfur. This material is primarily of research interest for optoelectronic and photovoltaic applications, where the layered sulfide structure and bandgap characteristics may offer advantages in light absorption or photoresponse. As a relatively unexplored compound, it represents the broader class of lead-free halide and chalcogenide perovskite alternatives being investigated to replace toxic semiconductors in next-generation solar cells, radiation detectors, and infrared sensing devices.
