Some issues of history and prospects of thermoelectricity

Abstract

A portable thermoelectric-power-generating module composed of oxide devices Abstract. This work analyzes the approaches that had led to the discovery of thermoelectricity and a generalized approach in the description of thermoelectric power conversion based on the induction of thermoelectric currents. Possibilities of thermal generators contribution to "green" technologies, in particular, to waste heat recovery from heat engines are analyzed. Tellurium problem and the ways of tackling it are considered. Attention is focused on the efficiency of computer methods for designing thermoelectric devices. The outlook for progress of thermoelectricity in measuring technique is considered. The information on the organizations and specialists in thermoelectricity is provided. The necessity of purposeful training specialists in thermoelectricity for its more successful development is emphasized.

Symmetry Analysis of Thermoelectric Energy Converters with Inhomogeneous Legs

“…It is seen that, in a heterogeneous leg, curl currents I c may arise, reducing the Z value of the thermocouple. 15 The curl current I c occurs near the sloping ( time, no curl current is observed near the orthogonal phase borders of segments (ra//I, rT, and Q) ( Fig. 2a and b).…”

Thermostabilized photodiode for monitoring radiation of medical lasers

“…Thermoelectric modules are rather efficient in this sense [13]. However, in our case, when using thermoselectric cooling, besides the problem of minimizing the nonlinearity of output performance at simultaneous enlarging the dynamic range of a photodiode, we face the task of producing the thermoelectric modules (TEM) with the time of reaching the operation mode 1…4 s. We should also achieve homogeneity of temperature distribution on the cold edge of TEM within 0.1…0.3 °С for uniform cooling the photodiodes with large areas of a photosensitive element.…”

On the Way to the Creation of Thermoelectric Converters on the Basis of Nanoobjects Such as Quantum Dots, Nanowires and Superlattices

“…Однак, ще донедавна вважалося, що саме для термоелектричних за-стосувань кремній зовсім не придатний. Справа в тому, що створення ефективних ТЕП висуває до сучасних матеріалів електронної техніки до-сить складні вимоги, які не обмежуються роз-глядом лише динаміки електронів, а в рівній мірі стосуються і фононної підсистеми [56][57][58][59]. Адже безрозмірний коефіцієнт термоелектричної до-бротності ТЕП, згідно з (1), визначається, окрім диференційної термоерс і електропровідності , ще й коефіцієнтом теплопровідності .…”
