Abstract A series of p-type Cu2SnSe3/xCu2Se (x = 0, 5, 10, 15, and 20 wt. %) composites were fabricated by spark plasma sintering, and the thermoelectric properties have been investigated in the temperature range 10–400 K. The crystal structure was evaluated by employing XRD analysis. Rietveld refinement was used to compute the amount of monoclinic and cubic phases in the composites, and the results revealed a decrease in the monoclinic phase with the increase in x wt. %. The measured thermoelectric properties of pristine as well as composites indicated that the introduction of Cu2Se leads to a simultaneous enhancement in electrical conductivity and reduction in thermal conductivity in Cu2SnSe3.
