Effect of Active Layer Thickness on Characteristics of P3HT:PCBM based Organic Solar Cells

In this work, an optoelectronic model is used to simulate P3HT:PCBM organic solar cells (OSCs). First, wecalibrate this model with an experimental P3HT:PCBM OSC. Second, we investigate the effect of active layerthickness on the performance of OSCs. Light absorption, exciton generation rate are determined. From the excitongeneration rate, we simulate current density-voltage curves and photovoltaic parameters such as short circuit current,open circuit voltage, fill factor and power conversion efficiency. Simulation results reveal that the optimumthickness ofactive layer is 80nm.
