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 ...
ACS Applied Energy Materials is a monthly peer-reviewed scientific journal that was established in 2018 by the American Chemical Society. It covers aspects of materials, engineering, chemistry, physics, and biology relevant to sustainable applications in energy conversion and storage. The editor in chief is Kirk S. Schanze. [1]
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 ...
Advanced Energy Materials is a peer-reviewed scientific journal covering energy-related research, including photovoltaics, batteries, supercapacitors, fuel cells, hydrogen technologies, thermoelectrics, photocatalysis, solar power technologies, magnetic refrigeration, and piezoelectric materials.
The journal is international; it is managed by NIMS, which was joined in 2014 by the Swiss Federal Laboratories for Materials Science and Technology (Empa). [1] Currently STAM is an electronic journal, its articles are continuously published online. Its sister journal, STAM Methods, has been launched in 2021. [2]
The journal covers all aspects of materials engineering broadly described as materials selection, design, processing, characterization, and evaluation. The scope includes all substances used in engineering applications with a tendency toward constituent materials that comprise a larger system.
