Abstract

For the low temperature applications of Bi ₂Te ₃ based thermoelectric power generators (TEGs), determination of low temperature material behaviors is important. In the temperature range of 100-375 K, temperature dependency of Seebeck coefficient and electrical conductivity of a Bi ₂Te ₃ based TEG are experimentally determined. Furthermore, for a constant temperature difference, the variation of maximum power output with the mean temperature is analytically examined based on the experimentally measured material properties. It is observed that 250 K seems a critical mean operating temperature for the considered Bi ₂Te ₃ module. Correlations for temperature dependency of material quantities are also given for the temperature region of 100-375 K. The results can be used for the low temperature applications of Bi ₂Te ₃ based TEGs.
