A Review on Thermoelectric Generators: Progress and Applications

open access: yesEnergies, 2020
A thermoelectric effect is a physical phenomenon consisting of the direct conversion of heat into electrical energy (Seebeck effect) or inversely from electrical current into heat (Peltier effect) without moving mechanical parts.

Reversible Thermoelectric Nanomaterials

open access: yesPhysical Review Letters, 2005
Irreversible effects in thermoelectric materials limit their efficiency and economy for applications in power generation and refrigeration. While electron transport is unavoidably irreversible in bulk materials, here we derive conditions under which reversible diffusive electron transport can be achieved in nanostructured thermoelectric materials via ...

The thermoelectric working fluid: thermodynamics and transport [PDF]

open access: yes, 2016
Thermoelectric devices are heat engines, which operate as generators or refrigerators using the conduction electrons as a working fluid. The thermoelectric heat-to-work conversion efficiency has always been typically quite low, but much effort continues ...

Thermodynamics of Thermoelectric Phenomena and Applications [PDF]

open access: yes, 2011
Fifty years ago, the optimization of thermoelectric devices was analyzed by considering the relation between optimal performances and local entropy production. Entropy is produced by the irreversible processes in thermoelectric devices.

On the thermoelectricity of correlated electrons in the zero-temperature limit [PDF]

open access: yes, 2004
The Seebeck coefficient of a metal is expected to display a linear temperature-dependence in the zero-temperature limit. To attain this regime, it is often necessary to cool the system well below 1K.

A flexible electromagnetic wave-electricity harvester

open access: yesNature Communications, 2021
Materials that can harvest electromagnetic (EM) waves and harness the resulting energy would have many applications. Here, the authors present a hybrid composite that produces thermoelectricity from the heating in the EM absorption under microwave ...

Improved Thermoelectric Cooling Based on the Thomson Effect [PDF]

open access: yes, 2012
Traditional thermoelectric Peltier coolers exhibit a cooling limit which is primarily determined by the figure of merit, zT. Rather than a fundamental thermodynamic limit, this bound can be traced to the difficulty of maintaining thermoelectric ...
