Progress in Application, Research and Properties Testing of Thermoelectric Materials

In the face of the impending problems of energy shortage and environmental pollution, the thermoelectric materials, as one of the functional materials for energy conversion and thermoelectric refrigeration, is not polluted to the environment, and is applied in thermoelectric devices without transmission parts. And the thermoelectric devices are working stably without noise and waste, and have long service life. Therefore the thermoelectric materials have a widely application prospect as environmental friendly functional materials. The progress in application and research of thermoelectric materials was briefly given, and the test method of thermoelectric performance and the relevant test standard were discussed especially. Finally, the development and application of test instruments of thermoelectric properties, including electric and thermal performance, were introduced.
