With more and more applications of solar photovoltaic (PV) in the field of solar energy harvesting, it becomes urgent and necessary to strengthen the utilization efficiency of solar photovoltaic systems. In recent years, thermoelectric generator (TEG) has attracted much attention by combining with PV to obtain enhanced PV performances. In this work, a PV-TEG hybrid system has been established and examined experimentally, including an industry size poly-silicon PV panel, thirty blocks of TEGs and forced circulating cooling for TEGs. The temperatures of PV, hot and cold sides of TEG, electric parameters of PV and TEGs were recorded to investigate the performances of PV-TEG hybrid system. The cooling flow velocity and bath temperatures of circulating cooling were taken into consideration as the main factors to influence the performances of PV-TEG hybrid system. The experiment results indicate that the combination of TEG leads to the increase of efficiency and output power of PV. Both the flow velocity and bath temperature of circulating cooling have remarkable impacts on the PV-TEG hybrid system. Under certain circumstances, the PV-TEG hybrid system with circulating cooling may be a choice to obtain higher PV performances.
