摘要：

For the low temperature applications of Bi2Te3 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 Bi2Te3 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 Bi2Te3 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 Bi2Te3 based TEGs. (C) 2012 Elsevier Ltd. All rights reserved.
