摘　　要：局部阴影遮挡会导致光伏组件输出功率下降,温度升高,严重的会导致光伏组件失效甚至起火,严重威胁光伏电站安全运行。本工作从晶硅太阳能电池反向击穿电压入手,着重分析了反向击穿电压对光伏组件输出功率的影响。结果表明:在相同的遮挡测试条件下,相较于PERC和TOPCon,具有低反向击穿电压的IBC串并联组件具有更低的功率损失,并且IBC组件的热斑温度更低。Local shadow shading can cause PV module output power to drop and temperature to rise,which can lead to PV module failure or even fire in serious cases,seriously threatening the safe operation of PV power plants.In this work,we focus on the effect of reverse breakdown voltage on the output power of PV modules,starting from the reverse breakdown voltage of crystalline silicon solar cells.The results show that under the same shading test conditions,IBC series⁃parallel modules with low reverse breakdown voltage have lower power loss compared with PERC and TOPCon,and the hot spot temperature of IBC modules is lower.
