Modelling and Parameter Extraction of PV Cell Using Single-Diode Model

Abstract

In this work, numerical solution of nonlinear equations using Newton Raphson method (NRM) and a modified Newton-Raphson Method (MNRM) are utilized to solve and find the real roots of a nonlinear equation based on a single-diode PV cell. The proposed methods to solve nonlinear examples and obtain results with various values of a load resistance have been examined. The purpose of this paper is to obtain the results of solar cell parameters using two mathematical models with the comparison between them. The obtained results showed the proposed method (MNRM) is a powerful tool, sufficient way to solve this model with a least iterations.
