Abstract

Thermoelectric energy conversion is usually based on the longitudinal Seebeck and Peltier effects. These effects are manifest in so-called thermocouples, each consisting of a negative and a positive thermoelement. A single thermocouple is capable of handling only a small amount of power at a very small voltage whether it is used in the generation or refrigeration mode. For this reason, practical thermoelectric devices commonly consist of thermoelectric modules made up of a great many thermocouples. Even more complex structures are required when the performance is enhanced using a cascade. We shall see that the adoption of the transverse thermoelectric effects might enable much simpler arrangements to be employed.
