Enhancement of Efficiency of a TiO(2)-BiFeO(3) Dye-Synthesized Solar Cell through Magnetization

Enhancement in the efficiency of a TiO(2) dye-sensitized solar cell (DSSC) has been demonstrated by introducing ferromagnetic perovskite BiFeO(3) and controlling the magnetic field, which induces two-dimensional material-like properties in the bulk of the TiO(2)-BiFeO(3) DSSC (a 3-dimensional material). The effect of the concentration of BiFeO(3) as well as the magnetization direction on the performance of the TiO(2)-BiFeO(3) DSSC has been investigated. After magnetization, it was confirmed that the current density, efficiency, and open circuit voltage of the TiO(2)-BiFeO(3) DSSC were increased. The observed phenomena have been explained in terms of the Hall effect which is responsible for the reduction of the degree of freedom of the electron movement resulting in the two-dimensional material-like properties in the bulk of the TiO(2)-BiFeO(3) DSSC.
