Abstract
It is well established that weak applied magnetic fields of several tens of millitesla can lead to a change of several percent in the continuous-wave photocurrent in organic semiconductor devices. However, it remains to be determined whether the applied magnetic field modifies the photocarrier generation efficiency or its mobility or both. We use magnetic-field-dependent time-of-flight spectroscopy to disentangle these two possibilities. We find evidence that the magnetic field leads to a decrease in the photocarrier time-of-flight.
