Pulsed Spray Pyrolysis for High-Quality Bismuth Ferrite Thin Films: Bi Content Enabled Tuning of Photoresponse, Ferroelectric Domains, and Charge Separation for Energy Harvesting Applications
states, as confirmed by X-ray photoelectron spectroscopy (XPS), which has a significant impact on the material's polarization. The 5 at % Bi-rich film exhibits larger ferroelectric domains compared to the stoichiometric BFO sample, with a transient responsivity of 0.173 mA/W. Furthermore, the fabrication of a single-layer device and the assessment of a suitable electrode for charge carrier separation were studied. The asymmetric electrode configuration enhanced the photoresponse of the device. The study highlights the potential of BFO to be incorporated into the perovskite solar cell device structure with Bi content playing a crucial role in controlling the functional properties of BFO.
