Evaluation System for Figure of Merit of Thermoelectric Devices

Year: 2011

Type: article

Abstract: The apparatus for evaluation of the figure of merit (ZT) of thermoelectric devices has been developed in order to investigate the performance of the thermoelectric devices.ZTvalue is comprised of three physical quantities, Seebeck coefficient, electrical conductivity, and thermal conductivity. In this study, we present new apparatus developed for evaluating theZTand power generation efficiency of devices by direct measurement of thermal conductivity using guarded hot plate (GHP) method. The measuredZTvalues and power generation efficiency of the thermoelectric devices are presented.
