Optimizing polymer bulk heterojunction solar cells requires a fine tune over the thickness, weight ratio, and the morphology because of the strong coupling among light absorption, exciton dissociation, and charge carrier transport within bulk heterojunctions. Without guidance from modeling and simulation, it will be a daunting challenge to optimize the device performance. In this paper, we present...

The thickness of organic solar cells (OSCs) has been optimized by simulating current-voltage (J-V) behavior. Because the thickness of active layer (several hundred nanometers) in OSCs is comparable with the illumination wavelength, optical transfer matrix is applied to rigorously determine the optical electric field in thin-film devices, which is strongly affected by the optical interference. The...
