Abstract [en]

For the low temperature applications of Bi2Te3 based thermoelectric power generators (TEGs), determinationof low temperature material behaviors is important. In the temperature range of 100–375 K, temperaturedependency of Seebeck coefficient and electrical conductivity of a Bi2Te3 based TEG areexperimentally determined. Furthermore, for a constant temperature difference, the variation of maximumpower output with the mean temperature is analytically examined based on the experimentallymeasured material properties. It is observed that 250 K seems a critical mean operating temperaturefor the considered Bi2Te3 module. Correlations for temperature dependency of material quantities arealso given for the temperature region of 100–375 K. The results can be used for the low temperatureapplications of Bi2Te3 based TEGs.
