Abstract The rate of Frenkel exciton dissociation in P3HT:PCBM bulk-heterojunction organic solar cell was calculated using the newly derived interaction operator between charge transfer exciton and molecular vibrational energy. The PCBM LUMO energy levels were tuned to investigate their impact on the rate of dissociation of a Frenkel exciton into free pair of electron and hole. In the latter part of the study, the PCBM LUMO energy level was set to −4.10 eV and design optimization was performed on PET/PEDOT:PSS/TFB/ P3HT:PCBM/Ca bulk-heterojunction organic solar cell using the semiconducting thin film optics simulation software. Each of the layer thicknesses were optimized for maximum photon absorbance in the P3HT:PCBM active layer and a high power conversion efficiency of 7.46% was obtained.
