Summary: The exergo-economic analysis of a concentrated photovoltaic-thermoelectric generator (CPV-TEG) hybrid system showed that the system is more cost effective compared to using a concentrated photovoltaic (CPV) system alone. Optimization results indicated that integrating CPV and TEG may not be feasible in certain operating conditions.

Summary: This study investigates the optimization problem of the PV-TEG hybrid system using a multi-objective genetic algorithm and a CFD model. It is found that the output power and conversion efficiency of the PV-TEG system are significantly improved through optimization design, and the cooling condition and the use of TEG play important roles in the system performance. Furthermore, a multiple-criteria decision-making approach is applied to balance output power and conversion efficiency, and the best compromise solution is obtained.
