Enhancement of Efficiency of a TiO₂-BiFeO₃ Dye-Synthesized Solar Cell through Magnetization.

ABSTRACT: Enhancement in the efficiency of a TiO₂ dye-sensitized solar cell (DSSC) has been demonstrated by introducing ferromagnetic perovskite BiFeO₃ and controlling the magnetic field, which induces two-dimensional material-like properties in the bulk of the TiO₂-BiFeO₃ DSSC (a 3-dimensional material). The effect of the concentration of BiFeO₃ as well as the magnetization direction on the performance of the TiO₂-BiFeO₃ DSSC has been investigated. After magnetization, it was confirmed that the current density, efficiency, and open circuit voltage of the TiO₂-BiFeO₃ DSSC were increased. The observed phenomena have been explained in terms of the Hall effect which is responsible for the reduction of the
