We have developed single leg model using COMSOL Multiphysics® software to compute Φ of TE materials without using conventional ZT parameters. The Φ were calculated using parametric programming in PDE by using special probe to capture change in power (∆P), ΔT, and area (A), thus (Φ = ∆P/A*ΔT 2). The obtained results showed that the TE material with highest Φ when the temperatures are between 375 K and 550 K are n-type SiGe, and p-type SiGe. When the temperatures are between 550 K and 780 K, the TE materials with the highest Φ are PbTe-Pbl2, PbTe-CdTe, and PbTe-SrTe-Na. This work has shown that COMSOL Multiphysics is a powerful tool for analysis of TE materials and can be used to predict Φ without using conventional ZT.
