中文摘要：
以MATLAB软件为仿真平台，建立了光伏电池反向Bishop子电路模型，不同光照和不同温度下光伏电池电气特性的仿真和实验结果对比证明了该模型的有效性。分析了光伏组件模型各个参数对光伏电池电气特性的影响，对模型的参数提取和实际光伏阵列设计具有指导意义。大面积光伏阵列可能会出现热斑效应，利用光伏电池反向模型，分析了热斑效应形成原因、形成条件以及旁路二极管对热斑效应的进行了仿真分析，为并联旁路二极管拓扑结构的选择提供了依据。此外，仿真分析了实际商用光伏阵列在遮挡情况下所出现的多波峰特性，验证了旁路二极管对光伏阵列的保护效果。
英文摘要：
The Bishop reverse sub-circuit model of photovoltaic cell was built up in the simulation platform of MATLAB. The accuracy of the model under different insolation and temperature was verified by the comparison between the simulated and experimental results. The influence of the parameters in the model to the electrical characteristics of PV module was analyzed, offering guidance to the parameter extraction and PV array designing. Hot-spot effect might happen to mass PV array. The reason and condition of the formation of hot pot effect were analyzed with the reverse model of photovoltaic （PV） cell. The inhibition to the hot-spot effect by both overlap and non-overlap bypass diode was simulated, offering an accordance for the choice of the topologic structure of paralleling bypass diode. Besides, multi-peak characteristics of commercial PV array when it was shadowed was simulated, and the protection effect of bypass diode to the PV array was verified.
