Abstract :The temperature of the photovoltaic modules is at the ambient temperature at sunrise, and the cell temperature increases during the day depending on the radiation intensity and the active cooling system. This increase in cell temperature causes a loss of efficiency in the PV panel. For this reason, PV panels are being tried to be cooled by different methods. This study covers creating a hybrid PV panel system that can generate electricity by the Seebeck effect of thermoelectric generators while cooling the overheated photovoltaic panel. With the hybrid structure created, both prevent the efficiency decrease caused by overheating in photovoltaic panels and electricity generation with a thermoelectric generator while cooling PV panels were examined. In the study, the average temperature of the PV/T panel system without a thermoelectric module was 45℃, and the average temperature of the PV/T hybrid structure using thermoelectric was 47℃. The thermoelectric generator\'s hot and cold surface temperatures were tested at 43℃ and 42℃, respectively.
