Abstract: The efficiency of organic solar cells can be increased by stacking several OPVCs and connecting them in series to optimize the absorption of the incident light. In this study, researchers report the results on the optical modelling of a multi-layer organic photovoltaic device in which the incident light of sun is absorbed in the active layer. The influence of the optical parameters and thicknesses of different layers had been taken into account to improve the device performance. A composites of poly (3-hexylthiophene) (P3HT)/6, 6-Phenyl C61-Butyric acid Methyl ester (PCBM) blends are used as photo-active materials, sandwiched between a transparent Indium Tin Oxide (ITO)-electrode and a metallic (Ca, Al, Ag) backside contacts. This study aims to show optical effects of an extra interfacial layer of poly (3, 4-ethylenedioxythiophene)/(poly (styrenesulfonate) (PEDOT/PSS) on top of the ITO-electrode and a BCP layer on the metallic electrode. The objective is the use of some recent methods which make it possible the description of the electric field distribution for the organic solar cells described previously with different deposited layers to make a rigorous modelling of these devices. The basic criterion for optical optimization is to maximize the energy absorption in the active layer according to the distribution of electrical field on the device to enhancing the dissociation rate.
