· JVASP-155376· Cu2GePbSe4

Cu2GePbSe4 is a quaternary chalcogenide compound belonging to the metal chalcogenide family, combining copper, germanium, lead, and selenium in a single phase material. This is a research-stage compound primarily investigated for thermoelectric and photovoltaic applications, where the combination of heavy elements (Pb, Ge) and chalcogen chemistry offers potential for tunable band gaps and phonon scattering to improve energy conversion efficiency. While not yet widely commercialized, compounds in this material class are being explored as alternatives to traditional thermoelectric materials (bismuth tellurides, skutterudites) and emerging photovoltaic absorbers, particularly where moderate operating temperatures and cost-effectiveness are design constraints.
