AN EFFICIENCY OPTIMIZATION OF A POLYSILICON PHOTOVOLTAIC MODULE USING A 2-D ANALYTICAL AND A TWO-DIODEI-V MODEL FOR AN ILLUMINATED SOLAR CELL

34258

A two-dimensional (2D) analytical model based on the Green’s Function method is applied on a n+-p polysilicon solar cell. This model is implemented through a simulation program in order to optimize the conversion efficiency of a PV module constituted of 36 solar cells connected in series. The influence of different physical and geometric parameters like doping density and thickness of different regions of the elementary cell on the conversion efficiency. This study shows that the optimum conversion efficiency of the considered PV module can reach 19,38 %. A half-analytical method was investigated while using a two diode I-V model to predict the five electrical parameters that characterize the I-V relationship of PV module. These results are in satisfactory agreement with the simulation model of other works.
