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 Peltier effect can be used to create a heat pump. Notably, the Peltier thermoelectric cooler is a refrigerator that is compact and has no circulating fluid or moving parts. Such refrigerators are useful in applications where their advantages outweigh the disadvantage of their very low efficiency.
The main disadvantage of Peltier coolers is low efficiency. It is estimated that materials with ZT>3 (about 20–30% Carnot efficiency) would be required to replace traditional coolers in most applications. [81] Today, Peltier coolers are only used in niche applications, especially small scale, where efficiency is not important. [131]
The typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from bismuth telluride (Bi 2 Te 3), lead telluride (PbTe), [10] calcium manganese oxide (Ca 2 Mn 3 O 8), [11] [12] or combinations thereof, [13] depending on application temperature.
Refrigeration is any of various types of cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is ejected to a place of higher temperature). [1] [2] Refrigeration is an artificial, or human-made, cooling method. [1] [2]

The fight for Peltier's freedom, which is embroiled in the Indigenous rights movements, remains so robust nearly half a century later that “Free Peltier” T-shirts and caps are still hawked online.
1834 – Jean-Charles Peltier discovers the Peltier effect; 1844 – Charles Piazzi Smyth proposes comfort cooling [10] c.1850 – Michael Faraday makes a hypothesis that freezing substances increases their dielectric constant. 1851 – John Gorrie patented his mechanical refrigeration machine in the US to make ice to cool the air [11] [12]
