A simple technique for determining the Seebeck coefficient of thermoelectric materials

Journal of Physics E Scientific Instruments 11/2000; 19(11):921. DOI: 10.1088/0022-3735/19/11/008

ABSTRACT It is shown that the Seebeck coefficient of a semiconductor against copper can be determined in terms of that for a copper-constantan thermocouple by means of a rapid potentiometric measurement. Values obtained for typical samples of bismuth telluride alloy, using the apparatus that is described, are compared with those given by a conventional method and indicate that the technique is perfectly satisfactory.

    ABSTRACT: Precise calculation of parameters of thermoelectric modules and thermoelectric devices under operating conditions by present methods is very difficult. In this study, a new method is developed to calculate all parameters of thermoelectric modules. This new method makes it possible to determine the dynamic parameters of a real thermoelectric module operated under different working regimes. Measurement of thermoemf created by an operating module is the basis of this new method. An unloaded thermoelectric module, whose dynamic output parameters are necessary in the design of a medical helmet for the cooling of brain, has been investigated using this new method. A special device has been designed and realized to be used in these investigations.

    ABSTRACT: An experimental setup is developed for the measurement of the Seebeck coefficient of thin wires and thin films in the temperature range of 300-650 K. The setup makes use of the integral method for measuring the Seebeck voltage across the sample. Two pointed copper rods with in-built thermocouples serve as hot and cold probes as well as leads for measuring the Seebeck voltage. The setup employs localized heating and enables easy sample loading using a spring loaded mounting system and is fully automated. Test measurements are made on a constantan wire and indium tin oxide (ITO) thin film for illustration. The Seebeck voltage obtained for constantan wire is in agreement with the NIST data for copper constantan couple with an error of 1%. The calculated carrier concentration of ITO film from the Seebeck coefficient measurement is comparable with that obtained by electrical transport measurements. The error in the Seebeck coefficient is estimated to be within 3%.

    ABSTRACT: In the present study, a new method for searching all exit parameters of the thermoelectric module has been realized. The new method is based on measurement of thermo-emf of a working module and comparing the results obtained with those of classical methods. The new method is used for investigation of the values of parameters of a standard thermoelectric module of Melcor with production code of CP1.0-127-05L, used in medical coolers for renal hypothermia. The theoretical results calculated by the means of new and classical methods for the parameters of an actual thermoelectric module have been compared with the experimental results and the advantage of the new method in terms of approximation accuracy has been proven.
