中文摘要：
针对光伏电池的短路和开路情况进行参数灵敏度分析,以确定光伏电池基本参数对光伏电池电气特性的影响。通过分析特定参数在局部点的参数梯度,借助符号运算软件MAPLE定量分析光照强度、温度以及模型中各个参数对光伏组件电气特性的影响。实现了对5种不同种类、不同品牌的单晶硅、多晶硅、铜铟镓硒（CIGS）光伏组件直流模型的参数提取工作,提取了对电气特性影响最大的5个参数。利用所提取的参数对光伏组件建模,实验结果验证了该模型具有较高的精确度。
英文摘要：
The parameter sensitivity of photovoltaic cell is analyzed under short circuit and open circuit conditions to determine the influence of its basic parameters on its electric characteristics. Software MAPLE is applied to quantitatively calculate the influence of irradiation,temperature and model parameters on the electric characteristics of photovoltaic module by analyzing the local parameter gradient of particular parameter. The parameters of DC model are extracted for five types of photovoltaic module：mono-erystalline silieon,poly-silicon photovohaic module and CIGS. Five most influencing parameters are selected in the photovohaic module modeling and the experimental results demonstrate the high accuracy of the designed model.
