摘要：

Charge transport measurements reveal non-Langevin recombination for KP115:PCBM organic photovoltaic devices. This rare but highly advantageous behaviour allows a long charge carrier drift length and thus devices with thick active layers retain a high fill factor. However, no clear correlation with morphology was found, indicating that the origin of non-Langevin recombination may be more complex than previously thought.
