Temperature dependent Performance material properties and thermal losses, which occur as conductive and radiative heat transfer, were considered in Thermal losses the finite element model. Effective material properties were invoked for understanding the influence of tem- Energy conversion efficiency perature dependence of material parameters and related adverse effects on the model TEG. It is shown that Effective properties analytical equations with effective properties can provide excellent estimation of the performance of a TEG over a broad...
