Friday Science Blogging: Peltier effect
(Elec.) The production or absorption of heat at the junction of two metals on the passage of a current. Heat generated by the passage of the current in one direction will be absorbed if the current is reversed.

The Peltier effect is the reverse of the Seebeck effect; a creation of a heat difference from an electric voltage.
It occurs when a current is passed through two dissimilar metals or semiconductors (n-type and p-type) that are connected to each other at two junctions (Peltier junctions). The current drives a transfer of heat from one junction to the other: one junction cools off while the other heats up; as a result, the effect is often used for thermoelectric cooling. This effect was observed in 1834 by Jean Peltier, 13 years after Seebeck's initial discovery.
