There are several lumped equivalent circuits that describe the behavior of PV cell. These lumped circuits may be with single-diode or double-diode implementation [4]. In this paper, the equivalent circuit based on single-diode model is considered [8, 5-7, 9]. The equivalent circuit of a single-diode PV cell is shown in Figure 1 [9]. The current source, Ipp, represents the cell photocurrent and the cell losses are represented by AR; and Rs, which are series and shunt intrinsic resistances of the cell respectively. The mathematical model of the PV cell is obtained by applying Kirchhoff current law on the equivalent circuit given in Figure 1 [10]. Then, the expression of the model is:
