Performance analysis of thermoelectric generator by using lead telluride, perovskites, skutterudites and tetrahedrites

Abstract

In this research paper performance analysis of thermoelectric generator by using lead telluride, perovskites, skutterudites and tetrahedrites has been proposed. The performance of thermoelectric materials and thermoelectric modules has been calculated. These thermoelectric materials were combined to make thermoelectric couple which will be used in thermoelectric generator. The performance analysis of these thermoelectric couples were simulated on COMSOL Multiphysics 5.2 software. The results indicated that Pb1-xMgxTe0.8Se0.2 and n-type PbTe, Pb1-xMgxTe0.8Se0.2 and CoSb3-xTex, Pb1-xMgxTe0.8Se0.2 and CaMn0.98Nb0.02O3, Cu12Sb4S13 and CoSb3-xTex indicated higher efficiency than other thermoelectric couples. The proposed system can be utilized for varied range of applications for waste heat recovery and renewable power generation in automotive, industrial, power plants and space sector at an excellent efficiency and lower cost.
