Cs2Bi2Cd2S5
semiconductor· Cs2Bi2Cd2S5
Cs2Bi2Cd2S5 is a mixed-metal sulfide semiconductor compound combining cesium, bismuth, and cadmium in a layered crystal structure. This is a research-phase material studied primarily for optoelectronic and photovoltaic applications, where its tunable bandgap and potential for enhanced light absorption make it a candidate for next-generation thin-film solar cells and photodetectors. While not yet industrially established, compounds in this quaternary sulfide family are of interest as lead-free and cadmium-reduction alternatives to conventional perovskites and CdTe solar absorbers, though deployment requires further optimization of stability and device integration.
