The Seebeck and Peltier effects are different manifestations of the same physical process; textbooks may refer to this process as the Peltier–Seebeck effect (the separation derives from the independent discoveries by French physicist Jean Charles Athanase Peltier and Baltic German physicist Thomas Johann Seebeck). The Thomson effect is an ...
Thomas Johann Seebeck (German: [ˈtoːmas ˈjoːhan ˈzeːbɛk]; 9 April 1770 – 10 December 1831) was a German physicist who observed a relationship between heat and magnetism. Danish physicist Hans Christian Ørsted later called this phenomenon the thermoelectric effect .
The Seebeck coefficient (also known as thermopower, [1] thermoelectric power, and thermoelectric sensitivity) of a material is a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material, as induced by the Seebeck effect. [2]
A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect). Thermoelectric generators function like heat engines, but are less bulky and have ...
The efficiency of a thermoelectric device for electricity generation is given by , defined as =.. The maximum efficiency of a thermoelectric device is typically described in terms of its device figure of merit where the maximum device efficiency is approximately given by [7] = + ¯ + ¯ +, where is the fixed temperature at the hot junction, is the fixed temperature at the surface being cooled ...
As a result of the above, the four thermoelectric effects are correctly attributed the following names: Effect 1 is the Seebeck effect. Effect 2 is the Peltier effect - and is correctly identified as the reverse of the Seebeck effect. Effects 3 and 4 together comprise both "directions" of the Thomson effect.
Thomas Johann Seebeck (1780–1831) discovered the thermoelectric effect in 1821. The symmetrical Peltier effect ( Jean Charles Athanse Peltier , 1785–1845) uses an electric current to produce temperature differences.
It should begin with the three traditional thermoelectric effects (Seebeck, Peltier, and Thomson). There should also be a brief mention of the figure-of-merit with links to the literature, since considerations of this quantity have an important influence on the community of scientists focusing on developing the new generation of thermoelectric ...
