· JVASP-9736· Cu3PSe4

Cu3PSe4 is a quaternary compound semiconductor belonging to the chalcogenide family, combining copper, phosphorus, and selenium in a fixed stoichiometric ratio. This material is primarily investigated in research and development contexts for optoelectronic and photovoltaic applications, where its direct bandgap and photoresponse properties offer potential advantages over traditional silicon-based devices. Cu3PSe4 and related copper chalcogenide compounds are of particular interest for thin-film solar cells, photodetectors, and thermoelectric energy conversion, though commercial deployment remains limited compared to established alternatives like CdTe or CIGS absorbers.
