Recent advances by some researchers and companies in low-cost thermoelectric materials have resulted in significant commercial promise for ATEGs, [18] most notably the low-cost production of tetrahedrite by Michigan State University [19] and its commercialization by US-based Alphabet Energy with General Motors. [20]
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 ...
He received the 2009 R&D 100 Award from R&D Magazine for work on advanced thin film thermoelectric materials and transfer of technology to industry. The R&D 100 Awards are presented each year by the Magazine to identify the 100 most significant newly introduced research and development advances in multiple disciplines.
Researchers are trying to develop new thermoelectric materials for power generation by improving the figure-of-merit zT. One example of these materials is the semiconductor compound ß-Zn 4 Sb 3 , which possesses an exceptionally low thermal conductivity and exhibits a maximum zT of 1.3 at a temperature of 670K.
A sketch of the design problem. The aim of the design problem is to spatially distribute two materials, Material A and Material B, to maximise a performance measure such as cooling power or electric power output Design evolution for an off-diagonal thermoelectric generator. The design solution of an optimisation problem solved for electric ...

Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy.
Thermoelectric heat pumps can be easily used for both local acclimatization for removing local discomfort situations. [14] For example, thermoelectric ceilings are today in an advanced research stage [ 15 ] with the aim of increasing indoor comfort conditions according to Fanger, [ 16 ] such as the ones that may appear in presence of large ...
