A polymer phase separation model based on Cahn-Hilliard equation and a three-dimensional (3D) coupled exciton/electron/hole transport model in the disordered, phase-segregated morphology so generated, allow us to predict, possibly for the first time, the morphology dependent performance limits of polymer/fullerene bulk heterostructure (BH) solar cells. We relate the optimum anneal time to polymer sizes, solvent content, film thickness, and anneal temperature and find that a regularization of the morphology can double the efficiency of BH cells.
