A new approach is presented in this work, to extract electrical parameters of a photovoltaic cell, using the double exponential model. The equivalent circuit parameters of this model are the photocurrent (Iph), ideality factor (?), diffusion current (Iod), recombination current (Ior), series resistance (Rs) and the shunt resistance (Rsh). Several research studies have been performed to extract these parameters. The majority of these developed methods are limited on several levels. In this work the proposed technique is based on the equalization of the electric model of photovoltaic cells, and a polynomial model equivalent. The comparison of these two models at I=0, allows representing the electrical parameters with the polynomial model coefficients. This method is tested on a monocrystalline solar panel and obtained results show the advantage of this technique in level of speed, convergence and precision.

Abstract
A new approach is presented in this work, to extract electrical parameters of a photovoltaic cell, using the double exponential model. The equivalent circuit parameters of this model are the photocurrent (Iph), ideality factor (?), diffusion current (Iod), recombination current (Ior), series resistance (Rs) and the shunt resistance (Rsh). Several research studies have been performed to extract these parameters. The majority of these developed methods are limited on several levels. In this work the proposed technique is based on the equalization of the electric model of photovoltaic cells, and a polynomial model equivalent. The comparison of these two models at I=0, allows representing the electrical parameters with the polynomial model coefficients. This method is tested on a monocrystalline solar panel and obtained results show the advantage of this technique in level of speed, convergence and precision.
