Abstract

We have investigated an analytic model that describes the light absorption and carrier transport in bulk heterojunction organic solar cells based on poly (3-hexylthiophene): (6, 6) - phenyl-C61-buteric-acid-methyl ester (P3HT:PCBM) blend. In order to calculate the power conversion efficiency (PCE) the current-voltage characteristics is analyzed and plotted by varying the active layer thickness, a device with higher PCE is obtained. We inserted the metal nanoparticles (MNPs) inside the active layer and studied the device structure using Finite Difference Time Domain (FDTD) method. Considering the proposed model, we observed that, the absorption coefficient and PCF are increased considerably.
