In this study, magnetic field (B) was applied on TiO(anatase) of dye-sensitized solar cell (DSC) for alignment of crystal. Magnetic field was applied on TiOwhen deposited TiOon the fluorine tin oxide (FTO) was dried at 373 K for crystalline orientation. And applying time of B was varied 025 min. Characteristics of the magnetic field applied TiOfilms were analyzed by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS). Current-voltage characteristics were also analyzed using solar simulator, and it was confirmed that the energy conversion efficiency of 41% was increased. Finally, it was identified that the magnetic field affected orientation of TiO resulting in the enhancement of the performance of the DSC.
