Abstract

The work presents the results of experimental studies of thin film thermoelectric generators based on quaternary compounds PbSnAgTe and doped PbTe:Sb in the temperature range of 300–450 K. It is shown that the selected chemical composition Pb₁₄Sn₄Ag₂Te₂₀/PbTe:Sb and the technological processing parameters make it possible to obtain 5-µm thin films with low internal resistance and a high Seebeck coefficient, which ensures high thermoelectric power and long-term stability. The conversion efficiency of the studied thin film thermoelectric generator with 3.5 pairs of Pb₁₄Sn₄Ag₂Te₂₀/PbTe:Sb at a temperature difference of 100 K was 4.7%.
