摘　　要：光伏电池的性能受到太阳能电池内部温度升高的严重限制。从太阳能电池中取出或储存多余的热能是提高能源效率的关键。为了解决这个问题,相变材料(PCM)被集成到风冷双通道光伏/热(PV/T)系统中。利用ANSYS CFD建立了该模型并对其进行了验证,出风口温度的最大误差分别为1.1%。将结果与集成PCM的风冷单通道、未集成PCM的风冷单通道PV/T系统进行对比,表明集成PCM的双通道设计对PV/T系统性能有显著影响,14:00系统性能最高时总效率可达到71.8%。该研究为优化PV/T系统的性能提供了有价值的见解,有助于提高太阳能的利用率。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 temperature 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.
