applications now and in the future, but also with a challenge to increase thermoelectric devices' performance. The phenomenon is described by three effects. The Seebeck effect. -discovered by Thomas Seebeck- in 1821 is the conversion of temperature difference into electrical voltage. The Peltier effect -discovered by Jean
The Peltier effect can be considered as the back-action counterpart to the Seebeck effect (analogous to the back-emf in magnetic induction): if a simple thermoelectric circuit is closed, then the Seebeck effect will drive a current, which in turn (by the Peltier effect) will always transfer heat from the hot to the
In this book we shall review the physical aspects of an energy conversion process that does not require any mechanical movement. The thermoelectric phenomena in those solids that conduct electricity are a measure of the energy transported by the charge carriers. These effects are thermodynamically reversible but they
The first of the thermoelectric effects was discovered in 1821 by T.J. Seebeck. He showed that an electromotive force could be produced by heating the junction between two different electrical conductors. The Seebeck effect can be demon- strated by making a connection between wires of different metals (for example,.
The Peltier coefficient depends on the pair Page 7 of materials A and B of the junction and also on the junction temperature. William Thomson (later well known as Lord Kelvin) discovered a third thermoelectric effect which provides a link between Seebeck effect and Peltier effect.

Seebeck and Peltier Effects. Introduction. Thermal energy is usually a byproduct of other forms of energy such as chemical energy, mechanical energy, and electrical energy. The process in which electrical energy is transformed into thermal energy is called Joule heating. This is what causes wires to heat up when current
Abstract: A simple model system is generated to derive explicit thermoelectric effect expressions for. Peltier, Seebeck and Thomson. The model applies an n-type semiconductor junction with two different charge-carrier concentration nL and nR. Peltier effect and Seebeck effect are calculated by applying a reversible closed
