Components of a thermoelectric generator.
The Seebeck effect was discovered by the German physicist Thomas Johann Seebeck in 1821.1
He observed that when two different conductive materials are joined to form a closed circuit, an electric current flows through the circuit if the two junctions are maintained at different temperatures. This phenomenon serves as the fundamental principle behind thermoelectric power generators, which convert temperature differentials directly into electricity.123
