Abstract—The parameters of micromodules for thermoelectric generators used at low heat fluxes have been calculated. For the branches of micromodules, our own developments of fine-crystalline materials based on the Sb2Te3–Bi2Te3 solid solution of p-type conductivity and the Bi2Te3–Bi2Se3 solid solution of n-type conductivity obtained by hot pressing and extrusion of powders prepared by grinding an ingot and by the melt rapid crystallization methods, that is, by melt spinning and crystallization of melt in a liquid, are considered. Calculations of the dependence of micromodule power on the temperature difference, thermoelectric properties (the Seebeck coefficient, specific electrical conductivity, and thermal conductivity) of p- and n-branch materials, their number, cross-section, and height at the cold junction temperature of 17°C have been carried out. It was found that the generated power of the module is directly proportional to the cross-sectional area and inversely proportional to the height of the module branches.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
