Investigation of Recombination Process of P3HT: PCBM Organic Solar Cell

Abstract:

We applied an effective medium model for a computational study and investigated a recombination mechanism in a P3HT:PCBM bulk heterojunction (BHJ) organic solar cells where the main assumption is the p-n nanostructure is treated as one single effective semiconductor layer, and parameters in this configuration are fed into a standard solar cell device simulator, called a Solar Cell Capacitance Simulator (SCAPS). Using SCAPS, the electrical performances of organic solar cells and the intensity-dependent current density -voltage (J-V) were simulated and compared with the actual experimental result. The results show that they are in good agreement with each other and monomolecular recombination mechanism is the dominant mechanism in the BHJ organic solar cells.
