Progress in Research on Functionally Graded Thermoelectric Materials
Abstract:In order to enhance thermoelectric properties of the monolithic thermoelectric materials, a few will monolithic thermoelectric materials prepared by linking into the structure of the thermoelectric gradient materials, materials not only solved the narrow application of temperature, and can greatly improve the thermoelectric conversion efficiency. In this paper. Thermoelectric gradient materials basis, the gradient materials design and optimization methods of thermoelectric gradient materials are reviewed and pointed out that segment thermoelectric materials to improve thermoelectric performance in the development of more advantages.
Keywords: functionally graded thermoelectric material thermoelectric conversion efficiency functionally graded design interface
