Solar panel can act as a medium for transforming sunlight into electrical energy. Nevertheless, not all of the sunlight received on this device can be converted into electrical energy and the remainder will be dissipated into thermal energy. If a solar panel is continuously exposed to the sun, so its temperature will increase and thereby reduce its electrical efficiency. To deal with the issue, it may combine a PV panel with a thermal collector which is called a hybrid PV/T collector. Furthermore, in the present study the effects of fluid flow direction and mass flow rate on the thermal and electrical efficiency of the PV/T collectors are extensively analyzed. Single and double pass collectors with rectangular plate fin absorber were attached to backside of the PV panel. They were tested using a solar simulator with different flow rate ranging between 0.01 and 0.05 kg/s of the working fluid. The results show that the use of double pass PV/T air collector increase its performance compared with the single pass one. The highest values obtained from this type collector are found to be 73.23% in the thermal efficiency and 10.16% in the electrical efficiency with the working fluid mass flow rate of 0.048 kg/s.

太阳能电池板可以作为将阳光转化为电能的媒介。然而，并非所有在该设备上接收到的阳光都可以转化为电能，其余的将耗散为热能。如果太阳能电池板持续暴露在阳光下，其温度会升高，从而降低其电效率。为了解决这个问题，它可以将光伏面板与集热器结合起来，称为混合 PV/T 集热器。此外，在本研究中，广泛分析了流体流动方向和质量流量对 PV/T 集热器的热效率和电效率的影响。带有矩形板翅式吸收器的单通道和双通道集热器连接到光伏面板的背面。使用太阳模拟器对它们进行了测试，其中工作流体的不同流速范围在 0.01 到 0.05 kg/s 之间。结果表明，使用双通道 PV/T 空气收集器与单通道相比提高了其性能。在工作流体质量流量为 0.048 kg/s 的情况下，发现从这种类型的集热器获得的最高值是热效率的 73.23% 和电效率的 10.16%。
