model parameter fitting

Solar cell both exponent mathematical model can be obtained exactly using a few measurement data by the least squares fitting method that parameter can be separated.

用参数可分离非线性最小二乘拟合方法，根据少量测量数据较准确地求得了太阳电池双指数数学模型。

Parameter of the model and the numerical solution are given using the way of curve fitting.

同时用曲线拟合的方式，给出了模型中参数的确定方法，以及模型的数值解法。

Finally, three methods have been proposed for model calibration, namely, index comparison, parameter comparison and curve fitting.

最后，提出了三种方法对模型进行校验，分别是指标对比法、参数对比法、曲线拟合法。
