Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
The flow of charge carriers between the hot and cold regions in turn creates a voltage difference. In 1834, Jean Charles Athanase Peltier discovered the reverse effect, that running an electric current through the junction of two dissimilar conductors could, depending on the direction of the current, cause it to act as a heater or cooler.

Besides passive heat conduction, active cooling consuming electricity can be achieved through the thermoelectric coolers. [5] When electrical voltage is added to an n-type (p-type) semiconductor material, the electric filed will drive electrons from one end to the other, which will also carry the electronic kinetic energy and entropy.
