The purpose of the work is multifactorial computer optimization of the composition, structure, and manufacturing technology of bismuth telluride based thermoelectric materials. Research methods are methods of mathematical physics to describe thermal and temperature fields, computer simulation methods to determine spatial distribution, experimental methods for optimizing technological processes for obtaining materials and measuring their parameters. Advanced computer models for the formation of the structure of Bi2Te3 based thermoelectric materials in the process of their production from melts and powders have been developed. The optimal composition of components of thermoelectric materials based on n- and p-type bismuth telluride has been determined and experimentally confirmed. The technological process and design of equipment for the production of Bi2Te3 based thermoelectric materials have been optimized, thus enabling obtaining structurally more advanced materials with an increased figure of merit and achieving a competitive advantage for consumer thermoelectric energy converters on the world market. The possibilities of using artificial intelligence methods to optimize thermoelectric materials and improve their quality are considered. Methods and equipment with increased speed have been developed for the experimental determination of the properties of Bi2Te3 based thermoelectric materials, which allows the formation of a sufficient and reliable database for the effective use of these capabilities. The results of the work have been introduced into the production of cooling modules for space purposes, whose characteristics exceed the world level.
