Effects of a Thermal Nonlinear Resistance on the Power Output of the PV Cell

Abstract

Within the existing approaches aiming to ameliorate the performances of the photovoltaic (PV) cell, we note that the nonlinear behaviour of the PV cell components is not exploited. In this paper, we examine the effects of a thermal nonlinear resistance on the characteristics of a PV cell known as the current-voltage I-V and power-voltage P-V. This thermal nonlinear resistance is constituted of a series resistance whose value varies as a quadratic function of the temperature across it. In the standard test condition and around this proposed model of the PV, analytical study and numerical simulations in MATLAB as well as experimental investigations with Multisim environment are made............
