Nanostructure engineering has improved the performance of thermoelectric materials, but the deteriorated stability of the materials at high temperatures shortens the service life of thermoelectric modules. Here, we realized a...

Energy shortage and environmental pollution have become severe problems that can not be ignored in every country. As a new energy conversion material, thermoelectric material can realize thermoelectric conversion with the advantages of safety, energy saving and environmental protection. This paper summarizes the progress of some PbTe based thermoelectric materials in recent ten years, including the influence of doping elements such as Na, S, Sr and I on their thermoelectric properties, and introduces a method to balance their mechanical and thermoelectric properties. It can be seen that PbTe based thermoelectric materials have good development and broad application prospects in the future.
