The object of the research is the thermoelectric method of cooling optoelectronic systems, the subject is thermoelectric coolers for optoelectronic systems in the IR spectrum range. The purpose of the work is to develop technologies for creating modern, reliable thermoelectric coolers for IR receivers, the energy performance of which would exceed that of their global counterparts. Rational models and their features were established. Taking into account the requirements for optoelectronic systems, computer methods and tools were developed for optimizing materials for thermoelements and designing structures of thermoelectric coolers with an extended operating temperature range and maximum energy efficiency. A process method for measuring contact resistance has been improved, and a setup for measuring contact resistance with an error of no more than 2% has been developed. New process methods for creating materials based on quasi-ternary solid solutions (Bi2Te3)1-x-y(Sb2Te3)x(Sb2Se3)y have been proposed for cascade coolers of IR receivers. Optimization of these materials is based on adjusting the composition, doping, and growth mode in accordance with the temperature conditions of each of the stages. New process methods and tooling have been developed for fabricating cascade modules without intermediate heat spreaders, improving cooler performance due to the absence of inter-stage thermal resistances. Тhe possibility of cooling IR detectors to 200 K and 250 K has been experimentally confirmed. Computer simulation of the characteristics of a new prototype six-stage module made of Bi2Te3-based materials with parameters optimized for each stage has proven that such a TEC is capable of cooling the IR receiver to a level of 180–190 K, which exceeds the capabilities of known global analogues.
