· JVASP-109750· GaCuSnSe4

GaCuSnSe4 is a quaternary semiconductor compound combining gallium, copper, tin, and selenium elements, belonging to the family of I-III-IV-VI semiconductors. This is primarily a research material under investigation for photovoltaic and thermoelectric applications, where its tunable bandgap and potential for earth-abundant, non-toxic device architectures make it notable compared to conventional cadmium-based or lead-based alternatives. The material is of particular interest to researchers developing next-generation thin-film solar cells and solid-state energy conversion devices, though it remains in early-stage development with limited commercial deployment.
