Abstract

The simplified modeling used to describe the energy behavior of a thermoelectric system does not take into account the Thomson effect. This hypothesis is no longer valid in the case where the temperature differences are high. As a result, it can induce significant errors in the estimation of performance, and in particular the maximum COP. The latter are generally expressed as a function of the merit factor, determined from the characteristics of the material. By integrating the Thomson effect, new expressions are defined defining the optimal operating conditions. It is observed that the Thomson effect is poorly taken into account in the case of the material studied (Bi2Te3), when the Seebeck coefficient is assumed to be constant. It is then necessary to add to the model the dependence with respect to the temperature of the faces of the Seebeck coefficient. A new merit factor is thus obtained, which is no longer an intrinsic property of the material, because it also depends on the temperature.
