“…The revision of works concerning PV/T devices shows that most of the latest reviews [2][3][4][8][9][10][11] refer to a single theoretical study [12] of single-channel PV/T device, which concluded that "the channel-below-transparent-PV design gives the best efficiency; but since the annual efficiency of the IV-on-sheet-and-tube design in a solar heating system was only 2% worse, and is easier to manufacture, this design was considered to be a good alternative." Another study [13] used a similar collector design coupling with linear Fresnel concentrator because, according to the results shown in [12], "it gives one of the best ratios of electrical to thermal efficiencies in high irradiance conditions."…”

The present article presents simulation results of a combined photovoltaic panel (PV) with natural flow single-channel thermal collector device (PV/T) for different thermal performance modes. The efficiencies of the PV/T and the same size photovoltaic panel are compared. Stress analysis was performed to realize the system's limitation and resistibility to hydrostatic pressure. At different modes of operation, the photovoltaic efficiency was 6-15% higher for PV/T than for PV. The photovoltaic efficiency of PV/T was less influenced by insulation than that of PV, and combined thermal and photovoltaic efficiency was higher in insulated PV/T. Because of the hydrostatic pressure of water, the proposed design PV/T can use only limited existing PV panels which is a big disadvantage compared to other designs.
