The performance of photovoltaic cells is severely limited by the increase in the internal temperature of solar cells.Removing or storing excess heat energy from solar cells is key to improving energy efficiency.To solve this problem,phase change materials(PCMs)are integrated into air-cooled dual-channel photovoltaic/thermal(PV/T)systems.The model was established and verified by ANSYS CFD,The maximum error in the outlet air tempera-ture is 1.1%,respectively.The results are compared with the air-cooled single-channel PV/T system with PCM and the air-cooled single-channel PV/T system without PCM,and the results show that the dual-channel design with PCM has a significant impact on the performance of the PV/T system,The total efficiency of the system can reach up to 71.8%at its peak performance at 14:00.The study provides valuable insights into optimizing the performance of PV/T systems,helping to improve the utilization of solar energy.
