Abstract

In this paper ITO/P3HT/PCBM/Al Organic Photovoltaic Cells (OPVs) are simulated and their performance parameters are evaluated. The IV characteristics, carrier concentrations, and band diagram are simulated at different applied voltages. Performance optimization of the device dimensions and material parameters are carried out. Maximum power of 28.3 W/m2 , efficiency of 2.8, a fill factor of 0.7, VOC of 0.66 V, and JSC of 6 mA/cm2 are obtained, assuming 1 kW/m2 irradiance with AM 1.5 solar spectrum. When OPV is subjected to constant illumination, with 2ൈ1022 cm-3s-1 photons absorption rate in the active layer, the obtained performance parameters are 33.6 W/m2 , 3.4, 0.7, 0.7 V, and 7.3 mA/cm2 for the maximum power, efficiency, fill factor, VOC, and JSC respectively..
