This research describes the synthesis of the ferroelectric perovskite Na0.02Bi0.98FeO3-δ by the ceramic method starting from the standardized preparation of the bismuth ferrite BiFeO3 structure in order to identify a material with possible improved properties for photovoltaic applications. The synthesized materials were characterized by X-ray Diffraction (XRD) technique to determine the effective synthesis conditions for six BiFeO3 samples obtained at different calcination temperatures and quantified by Rietveld® refinement of diffraction patterns, finding homogeneous phase formation at 810°C under laboratory conditions. The effective synthesis temperature allowed obtaining a stable perovskite-type material, doped with Na+ and its structural characterization by XRD showed a structural modification in the unit cell with respect to BiFeO3 due to the incorporation of sodium cation. The morphological characterization by scanning electron microscopy (SEM) of the new synthesized material showed the formation of two stable phases: Bi2Fe4O9 and Na0.02Bi0.98FeO3-δ as the predominant phase. The optical characterization by Raman spectroscopy allowed identifying variations in the vibration modes of the perovskite doped with respect to bismuth ferrite and the electrical characterization by solid state electrochemical impedance spectroscopy (SS-EIS) demonstrated an increase in electrical conductivity, at room temperature, by the Na+ doped perovskite proving an optimal behavior for its potential uses as a semiconductor. The results indicate that current methodology is promising to produce perovskites for photovoltaic applications.
