· JVASP-107018· ZnCu2SnSe2S2

ZnCu2SnSe2S2 is a quaternary semiconductor compound combining zinc, copper, tin, and chalcogen elements (selenium and sulfur), belonging to the family of mixed-metal chalcogenides. This material is primarily investigated in research contexts for photovoltaic and optoelectronic applications, where its tunable band gap and layered crystal structure offer potential advantages over traditional semiconductors in thin-film solar cells and light-emitting devices. Engineers consider this compound family when seeking cost-effective alternatives to conventional semiconductors with earth-abundant elements and enhanced performance in flexible or tandem photovoltaic architectures.
