The photovoltaic/thermal (PV/T) collector is an integration of PV cells and a solar thermal collector in a single unit, which is able to generate electrical and thermal energy simultaneously. Heat carriers, such as water or air, take in heat extracted from PV cells. The cells are then cooled, thereby improving the yield of electricity, as well as provid-ing thermal energy. Several investigations on PV/T collector/systems have been previously carried out.
