? 2022 Elsevier B.V.Harvesting waste heat into electricity through thermoelectric (TE) material can make a great contribution to reducing energy consumption and environment pollution. Cu2S has proved itself to be a highly promising TE material, whereas the poor electrical property restricts its practical application. Therefore, the way to improve its electrical property by doping elements with high carrier concentration in an environmental-friendly method accelerate its application. Herein, Ag nanoparticles are incorporated into a p-type Cu2S (Ag/Cu2S) by a facile hydrothermal method to improve the thermoelectric properties. The introduction of Ag can effectively tune the carrier concentration, resulting in a high power factor of 1698 μW m?1 K?2; meanwhile, Ag doping can also enhance the phonon scattering, further reducing the thermal conductivity. Eventually, a ZTmax peak value ≈ 1.4 @ 773 K is achieved in the 0.5 wt% Ag-doped Cu2S samples. The design principle for Ag/Cu2S composites opens up a new pathway for the synthesis and application of thermoelectric material.
