Cr2CdS4

Cr2CdS4 is a ternary chalcogenide compound combining chromium, cadmium, and sulfur—a material class of significant interest in semiconductor and photovoltaic research rather than established industrial production. This compound belongs to the family of metal sulfides, where the mixed-valence chromium and cadmium cations are coordinated by sulfide ligands, creating a structure with potential optoelectronic and catalytic properties. Applications remain largely in the research domain, focused on thin-film photovoltaics, light-absorbing layers in heterojunction solar cells, and photocatalytic water splitting, where cadmium chalcogenides and chromium-doped systems are explored for bandgap engineering and visible-light absorption.
