An organic photovoltaic device (OPV) with poly (3-hexylthiophene) (P3HT) absorber layer was designed and simulated
using SILVACO ATLAS software. The effective area of the cell was 6 mm2. Langevin recombination, a.singlet and s.binding
models were used to simulate this device. Under an illumination of one Sun (AM 1.5G, 100 mW/cm2), the simulated cell
showed an open-circuit voltage of 0.32 V, a short-circuit current density of 0.07 mA/cm2 and a fill factor of 29.5%, resulting
to a power conversion efficiency of 0.005%.
