History and Properties of Thermoelectric Devices
by a property known as the Seebeck coefficient, named after Thomas Seebeck who discovered the reverse effect in 1821 (as used in thermocouples and for power generation in thermoelectrics). In addition to the Seebeck coefficient, two other properties are important for optimization of thermoelectric
electricity via the Seebeck effect, where electricity is produced from a temperature differential applied across the device. The devices use a superthin, nanoengineered material that delivers a Seebeck coefficient 150% greater than conventional thermoelectric material. The grant will be used

New Materials for Thermoelectric Applications: Theory and Experiment
The important factors which determine the effi- ciency are the total thermal conductivity and the power factor of the thermoelectric material, which is given by the product of the electronic conductivity and the square of the Seebeck coefficient .
Unfortunately, polymer composites have been plagued by low operating efficiencies due to their low Seebeck coefficient .
The Seebeck coefficient α was then defined as the ratio between the induced voltage V and the temperature difference ΔT; α = V .
