Abstract
We have synthesized BiFeO3, Bi0.95Y0.05FeO3, Bi0.95Ho0.05FeO3, and Bi0.95Er0.05FeO3 compounds by the usual solgel route. The structural properties of the materials were characterized by X-ray diffraction (XRD). The optical properties were measured by UV-visible optical spectroscopy. The X-ray diffraction pattern and Reitveld refinement confirm the predominant BFO and rare earth doped BiFeO3 phases having rhombohedra structure with R3c space group. By doping BiFeO3 with rare earth ions (E, H, and Y), the optical band gap was tuned from 2.07 eV to 1.98 eV and thus falling under visible light range which could be promising for solar cell applications. We are proposing a photovoltaic device using rare earth doped BFO material with tuneable energy gap to enhance the probability of light absorption. The mechanism of operation of this kind of solar cell will be discussed.
