· Li2ZnSnSe4

Li2ZnSnSe4 is a quaternary semiconductor compound belonging to the chalcogenide family, combining lithium, zinc, tin, and selenium in a structured crystalline lattice. This material is primarily investigated in research contexts for photovoltaic and thermoelectric applications, where its tunable bandgap and ion-conducting properties make it attractive for next-generation solar cells and solid-state energy conversion devices. Compared to conventional binary semiconductors (like CdTe or CIGS), quaternary systems like Li2ZnSnSe4 offer enhanced flexibility in band structure engineering and potential for improved stability in thin-film photovoltaic or solid-state battery architectures.
