摘　　要：为探究不同遮挡因素对IBC组件发电量及温度的影响,采用PVsyst仿真模拟结合实验验证的方式对小面积遮挡、大面积遮挡及灰尘遮挡三种影响因素进行分析,并通过分析实验结论对组件结构进行重新设计。结果表明:IBC串并联组件阵列的每小时发电量比全串联组件阵列高0.12 kWh左右,新设计的双二极管接线盒IBC组件受阴影遮挡后的损失为常规串并联组件的1/2。In order to investigate the effects of different shading factors on the power generation and temperature of IBC PV modules,PVsyst simulation combined with experimental verification is used to analyze the three influencing factors of small-area shading,large-area shading,and dust shading,and the module structure is redesigned by analyzing the experimental conclusions.The results show that the hourly power generation of the IBC series-parallel PV module array is about 0.12 kWh higher than that of the full series-parallel PV module array,and the loss of the newly-designed dual-diode junction box IBC PV module after shading is 1/2 of that of the conventional series-parallel PV module.
