How Does a Thermo Electric Generator Work to Produce Power?

A thermoelectric generator (TEG) produces power by converting heat into electricity. The main components of a TEG include thermoelectric materials, heat exchangers, and electrical contacts.

First, the thermoelectric materials create a temperature difference when they are heated on one side and cooled on the other. This temperature difference causes Charge carriers, either electrons or holes, to move from the hot side to the cold side. This movement generates an electric current.

Next, the heat exchangers facilitate the transfer of heat to the thermoelectric materials. They must efficiently absorb heat from a heat source, like a combustion engine, and disperse heat from the cold side into the environment. This process maintains the necessary temperature gradient for the TEG to function.

Finally, electrical contacts allow the generated current to flow out of the TEG and be used to power external devices. The efficiency of a TEG depends on the properties of the thermoelectric materials, the temperature difference, and the design of the generator.

TEGs operate based on the Seebeck effect, which is the underlying principle that enables this conversion of heat into electrical energy.
