Abstract

See full text

A low-temperature high-performance thermoelectric material possesses a chemical formula of (AgyCu2−y)1−xTe1−zSez, wherein −0.025≤x≤0.075, 0.6≤y≤1.4, 0avg is in range of 0.2 to 1.4. The highest ZT value of this material at the room temperature is comparable to that of Bi2Te3, which is an excellent complement to existing low-temperature thermoelectric materials. At the same time, the present invention also indicates a new strategy to improve the low-temperature thermoelectric performance of Cu2X-based (here, X is S, Se, Te) materials, and lays a foundation for the application of Cu2X-based materials in the field of low-temperature thermoelectricity.
