Alignment of TiO2 (Anatase)‎ Crystal of Dye-Sensitized Solar Cells by External Magnetic Field

Abstract EN

In this study, magnetic field (B) was applied on TiO2 (anatase) of dye-sensitized solar cell (DSC) for alignment of crystal.

Magnetic field was applied on TiO2 when deposited TiO2 on the fluorine tin oxide (FTO) was dried at 373 K for crystalline orientation.

And applying time of B was varied 0~25 min.

Characteristics of the magnetic field applied TiO2 films 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 TiO2, resulting in the enhancement of the performance of the DSC.
