title = "Magnetic field effect on photocurrent in single layer organic semiconductor devices",
abstract = "We systematically studied the magnetic field effect on photocurrent (MPC) in ITO/N,N′-di(naphthalene-1-yl)-N,N′-diphenyl-benzidine (NPB)/Al sandwich devices as a function of the excitation photon energy and the applied bias voltage. We experimentally identified that the magnetic field induced an increase of intersystem crossing rate between singlet- and triplet- excitons (ISC-X) and a decrease of triplet exciton-polaron quenching rate (TPQ), with ISC-X was a high magnetic field effect and TPQ a low magnetic field one. It was found that the band alignment and carrier transport within the device played an important role in the MPC behaviors.",
