The work in this paper analyzes the configuration, limitations and performance of combining photovoltaic (PV) and thermoelectric generator (TEG) as a hybrid power source (HPS). The analysis method is based on relating the configuration of the HPS to its thermodynamic behaviour. A thermodynamic model of a TEG attached to a PV module, based on Matlab/Simulink, is built up. The PV and the TEG models were validated by comparing the simulation behaviour and the manufacturer's curves in the datasheets, and they had shown excellent compatibility to manufactures' experimental results. This technique is amicable to the PV module as it enhances its conversion efficiency and its applicability in electric vehicles (EV). It also enables the design of optimum HPS and improves the total generated power. The paper introduced the limitations and constraints in designing and using PV and TEG HPS. The different solar energy in different geographical locations applies different HPS configurations. The geographical locations with higher daily solar energy have also higher ambient and PV back temperatures. The advantage of using appropriate HPS configuration is its ability to lower the PV module back temperature and to harvest the waste heat and convert it to a usable electric energy. The simulation results showed the HPS modularity advantage in improving the conversion efficiency and its suitability for electric vehicles applications. The annual extra generated power in each square meter of horizontal surface can reach up to 11.66 kW and 2.24 kW, in Amman and Stuttgart; respectively.
