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 ...
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]
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.
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.
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.
Much faster computing for some kinds of problems, chemical modeling, new materials with programmed properties, Hypothetical of high-temperature superconductivity and superfluidity: Quantum cryptography: Commercialization [39] Secure communications Quantum radar: Prototypes Radio-frequency identification: Diffusion of high cost [40] [41] [42]
Recent experiment on nanowire solar cells has led to a remarkable improvement of the power conversion efficiency of SiNW solar cells from <1% to >17% in the last few years. [5] The ability for lithium ions to intercalate into silicon structures renders various Si nanostructures of interest towards applications as anodes in Li-ion batteries ...
Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
