· K2Sn3(SbS5)2

K2Sn3(SbS5)2 is a complex sulfide semiconductor compound combining potassium, tin, and antimony in a layered crystal structure. This is a research-phase material within the broader family of metal sulfide semiconductors, investigated for potential optoelectronic and thermoelectric applications where layered architectures can enable tunable band gaps and anisotropic transport properties. The combination of tin and antimony chalcogenides is of interest in next-generation photovoltaics and solid-state energy conversion, though industrial adoption remains limited compared to more established alternatives like CdTe or perovskites.
