How Thermoelectric Generators Work. Thermoelectric generators (TEG) are solid-state semiconductor devices that convert a temperature difference and heat flow into a useful DC power source. Thermoelectric generator semiconductor devices utilize the Seebeck effect to generate voltage. This generated voltage drives electrical current and produces ...

Thermoelectric technology can realize the reversible conversion of thermal energy to electrical energy. Huge low-grade heat energy (usually less than 200 °C) is difficult to be utilized by traditional heat engines, while comprehensive approaches to developing TE materials with high zT values at the low-temperature zone is an effective …

The piezoelectricity is used in pressure sensors; and pyroelectricity is used in thermal sensors. These electro-thermo-mechanical effects occur in polarized materials. Polarizable materials have such a lattice structure that the motion of atoms causes an unequal (heterogeneous) distribution of electric charge.

Thus, for a material to have a large thermoelectric effect, it must have a large electrical conductivity and small thermal conductivity. Thermoelectric devices are typically made from metals or semimetals because these materials satisfy this condition. The second effect was discovered by Jean Peltier in 1834 [5, p. 113].
