Thermoelectric generators are solid-state devices that help convert heat flow directly into electric voltage. Thermoelectric generators utilize the Seebeck effect where a temperature difference between two dissimilar conductors or semiconductors creates a voltage difference between them. Thermoelectric generators find widespread adoption in capturing waste heat from automotive exhausts, industrial processes, and other sources and converting it into usable electric power. Advancements in thermoelectric materials have significantly boosted the efficiency and performance of thermoelectric generators. Adoption of advanced thermoelectric materials like skutterudites, clathrates, and tin selenides has increased the thermoelectric figure of merit of generators, allowing more heat to be converted into electricity.
Global Thermoelectric Generator Market is estimated to be valued at USD 749.2 Mn in 2024 and is expected to reach USD 1568.3 Mn by 2031, growing at a compound annual growth rate (CAGR) of 11.1% from 2024 to 2031.
