· JVASP-110606· Cd2GaCuS4

Cd2GaCuS4 is a quaternary chalcogenide compound combining cadmium, gallium, copper, and sulfur into a ternary sulfide crystal structure. This is a research-phase material investigated primarily for optoelectronic and photovoltaic applications, particularly as an absorber layer in thin-film solar cells and as a potential material for nonlinear optical devices. While not yet in widespread industrial production, chalcogenide compounds of this family are valued for their tunable bandgaps and strong light-absorption properties, positioning them as alternatives to conventional silicon or CdTe solar cells in specialized high-efficiency or flexible device contexts.
