In this research work,  the performance parameters , such as fill factor (FF), external quantum efficiency (EQE) , maximum power density and carrier concentration profile of a planar hetero-junction poly 3-hexyl thiophene (P3HT) / phenyl-C61-butyric acid methyl ester (PCBM) photovoltaic cell has been simulated for different values of carrier mobility where the simulation has been performed under the consideration of incident solar radiation of 1 kW/m2 irradiance, air mass of 1.5, ambient temperature of 300K and indium tin oxide (ITO) and aluminium (Al)  has been considered as the anode and cathode of the P3HT/PCBM solar cell respectively.  The performance parameters has been determined for electron mobility of 5 × 10-4 , 5 × 10-3 , 5 × 10-2 and 5 × 10-1 (cm2/V.s) at  the acceptor and hole mobility of 1 × 10-4 , 1 × 10-3 , 1 × 10-2 and 1 × 10-1 (cm2/V.s) at the donor layer. Carrier concentration profile has been studied for 0.4 and 0.5 V junction voltage and for different values of carrier mobility. Finally highest external quantum efficiency of 2.413% and maximum power density of 24.13 W/m2 has been obtained for hole mobility of 1 × 10-1 (cm2/V.s) and electron mobility of 5 × 10-1 (cm2/V.s).
