A research object is thermo-electric semiconductor transformers of energy and physical and chemical processes that take a place on границі thermo-electric material is antidiffusive coverage - interconnect plate. A purpose of work is development of матеріалознавчих and technological bases of creation of high-quality composite structures with the beforehand set properties, development of methods of their connection with ceramic materials and thermo-electric materials for the thermo-electric transformers of energy of enhanceable efficiency which will provide growth of competition possibility of domestic thermo-electric products at the international market. The computer method of planning is developed on the basis of theory of optimum management enables to expect the parameters of resource firmness and reliability of contact and interconnect structures and get the contacts of new type. Planning was conducted both for the case of the extruded thermo-electric materials and single-crystal. In accordance with the results of planning party of the cascade thermo-electric modules was made. The results of experimental researches rotined that due to optimization of structure of contacts of new type the maintainance of power parameters of the cascade thermo-electric modules of cooling at substantial of growth of them is attained mechanical firmness. The calculations of mechanical and thermal напруг are conducted, that arise up in the thermo-electric devices of type a кристал-припій-тепловідвід is given possibility to define terms for which mechanical and thermal tension in the thermo-electric wares of the set geometry minimized. The technological methods of receipt of high-quality commutation of thermo-electric transformers are developed with an enhanceable resource and cyclic the experimental standards of the modules are Developed and made with the use of interconnect structures with minimized internal mechanical напругами. Experimental researches of resource firmness and of long duration reliability of the experimental великоформатних thermo-electric modules are conducted at a maximal working temperature +300 С and Т =25 С during 57th months. As a result of the conducted researches, worsening of parameters of the modules was marked максимум on 6,19%. Certainly the optimum technological modes are for the receipt of high-quality contacts both for extruded and single-crystal thermo-electric materials with high термоефективністю. The technological methods of creation of composition contact and interconnect structures of enhanceable reliability are developed. Research is conducted on creation of methods of treatment of surface of thermo-electric materials which provide high-quality connections with contact composition structures. The new technological method of previous preparation of surface of thermo-electric material and causing of high-efficiency antidiffusive layers is developed on the surface of THEMES which allowed to promote reliability of antidiffusive layers (адгезійна durability of coverage exceeds cohesive durability of material). High-quality coverages are got with high адгезійними and protective descriptions for the великоформатних thermo-electric transformers of energy of enhanceable efficiency. The row of high-efficiency thermo-electric transformers power descriptions of which on 10-15% are more high in comparing to the existent world analogues is created Keywords: THERMOELECTRICITY, THERMO-ELECTRIC TRANSFORMERS, COMPUTER DESIGN, CONTACT COMPOSITION STRUCTURES.
