    • tr as the time for carriers to be extracted from the device once they are created. for a bilayer device, this is the time it takes carriers to drift from the P3HT/PCBM interface where they are created to the electrodes, which should depend directly on the thickness of the organic layer that they traverse

    • We note that minimizing the carrier transit times is likely to be much more important in BHJ devices, where the strong degree of mixing of the two components allows recombination to have a significant role the longer carriers take to escape. Recombination is much less of an issue in bilayers, because oppositely charged carriers never re-encounter each other once they leave the P3HT/PCBM interface
