Abstract
We investigate the evolution of the vertical morphology in a solution-processed P3HT/PCBM “bilayer” organic solar cell using a combination of techniques, including neutron reflectometry. By correlating the device performance with the active layer morphology, we establish that the solution processed bilayer concept is a misnomer and sequential solution processing is an elegant way to make bulk heterojunction organic solar cells with high efficiency. © 2011, Wiley-VCH Verlag Berlin
