The thermoelectric material has a Seebeck effect, and when the temperature difference exists on two sides of the thermoelectric material, the potential difference can be generated on the two sides of the thermoelectric material, so that the heat energy can be converted into electric energy. Since the thermoelectric device can directly realize the interconversion between electric energy and heat energy, the thermoelectric device is mainly used for detecting temperature in the early stage, and is widely applied to the fields of electronic temperature control, waste heat power generation, aerospace battery packs and the like with the development of high-performance thermoelectric materials later.
The thermoelectric material power generation device is easy to maintain, energy-saving, environment-friendly, simple and stable. At present, thermoelectric technology is utilized to generate electricity by using industrial waste heat or temperature difference of automobile exhaust, and wide market prospect is gradually shown.
