(C) Maximum conversion efficiencies (hmax) as a function of temperature difference (DT) for the high-entropy segmented thermoelectric module in this work and some reported results from the literature, as indicated by the superscript. Some reported zT values for traditional n-type PbSe-based materials are also included for comparison (38–42). (B) zT values as a function of temperature for the high-entropy n-type PbSe-based materials in this work. The pink, red, green, blue, and purple spheres represent Pb, Sn, Se, Te, and S atoms, respectively. (A) Diagram of lattice distortion with increasing entropy. Improving the performance of thermoelectric materials and modules through entropy engineering.
