Sensitivity analysis and parameter extraction of photovoltaic cell model

Abstract

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-crystalline silicon,poly-silicon photovoltaic module and CIGS.Five most influencing parameters are selected in the photovoltaic module modeling and the experimental results demonstrate the high accuracy of the designed model.
