The research objects are thermopiles. The research purpose is to study the possibility of creating thermopiles intended for conversion of thermal energy of radioactive decay into electrical energy as part of miniature milliwatt-power radioisotope thermoelectric generators that are used as self-contained supply sources with service life of 10-20 years. The research methods include successive approximation methods, numerical methods with the use of computer technologies, calculation methods, physics methods of experimental research, processing and analysis of the results obtained. The components of thermopile heat exchange in the breadboard of radioisotopic thermoelectric generator have been determined. The thermopile design and its manufacturing technique have been optimized. The thermopile reliability has been improved by means of passive redundancy system providing its working capacity with a complete failure of part of the legs. Thermopile samples have been manufactured and their energy characteristics have been determined separately and as part of a counterpart of miniature radioisotope generator with the electric equivalent of a heat source. In their technical and economic performance the thermopiles in given temperature range compare well with the best foreign samples and have no analogs in Ukraine. The research work results can find application in the scientific and industrial enterprise in the form of a limited liability society "Altec-М".
