· K10Zn4Sn4S17

K10Zn4Sn4S17 is a quaternary sulfide semiconductor compound combining potassium, zinc, tin, and sulfur in a layered or framework crystal structure. This is a research-phase material investigated for its potential in optoelectronic and photovoltaic applications, belonging to the broader family of metal sulfide semiconductors that offer tunable bandgaps and earth-abundant constituent elements compared to conventional III-V or chalcogenide alternatives. Interest in such compounds stems from their potential for cost-effective thin-film solar cells, light-emitting devices, and photodetectors, though industrial deployment remains limited pending optimization of synthesis, stability, and device integration pathways.
