· K2ZnSn2Se6

K2ZnSn2Se6 is a quaternary semiconducting compound belonging to the chalcogenide family, combining potassium, zinc, tin, and selenium in a layered crystal structure. This is a research-phase material primarily investigated for optoelectronic and photovoltaic applications due to its tunable bandgap and potential for efficient light absorption and emission. The compound represents an emerging class of earth-abundant alternatives to traditional semiconductors, with particular interest in solid-state lighting, infrared detection, and next-generation thin-film photovoltaic devices where cost and resource availability favor tin- and selenium-based systems over cadmium or lead analogs.
