However, the power conversion efficiency (PCE) of the PSCs needs to be further improved to realize its full potentials. Researchers have demonstrated that PSCs by two-dimensional conjugated polymers as the electron donors exhibit improved performance in comparison to PSCs by one-dimensional conjugated polymers. In this study, we investigate magnetic field effect which is induced by magnetic nanoparticles (Fe3O4) in active layer in BHJ PSCs. We found that incorporation of MNPs in active layer can boost PCE to 9.86%, which is probably originated from the magnetic field effect and the coercive electric field induced by MNPs in the bulk. Noticeable increases in both short-circuit current and fill factor are observed. Transient photocurrent (TPC) measurement is conducted to observe the extraction time of every single charge carrier precisely. Data fitting gives the maximum charge carrier mobility for devices and it presents a clear picture of the charge carrier dynamics and how incorporation of MNPs benefits the devices from underlying physics. 2018-06-05 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1525107259345629 http://rave.ohiolink.edu/etdc/view?acc_num=akron1525107259345629 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
