Abstract :
Motivated by a report of an all-solution processed P3HT/PCBM `bilayer´ organic solar cell, we have investigated the vertical morphology by using a combination of techniques, including neutron reflectometry. By correlating the device performance with the active layer morphology, we establish that sequential solution processing is an elegant way to make high efficiency bulk heterojunction organic solar cells.
