Impact of Temperature on Dielectric Properties of BiFeO3 Nanoparticles for PV Applications

A perovskite-based semiconductor with unrealized promise in solar applications, memory technology, and traditional electronics is bismuth ferrite (BFO). Researchers may be inspired to investigate into this material for the construction of many speedier and more effective electronic devices by the nanotechnology-based data that can be gained from it. In this paper, we examined the use of FESEM (Field Emission Scanning Electron Microscopy) and XRD (X-Ray Diffraction) methods to photograph the microstructure and determine the molecular structure of crystalline materials, respectively. We concentrated on the dielectric characteristics of bismuth ferrite made by the Sol-gel process at three different temperatures. As a result, at three different temperatures, we discovered the tendency of the dielectric constant to increase in frequency. Dielectric properties are important because they offer a macroscopic perspective of the polarization and ferroelectric characteristics of BFOs, allowing us to get knowledge of the internal electric field created by remnant polarization, which aids in the separation of the EHPs produced by sunlight.
