Abstract

In the process of solar photovoltaic, ferroelectric semiconductors such as BiFeO<subscript>3</subscript> are found to be new class of materials as an alternative to traditional semiconductors for more energy generations. The efficient chare transformation as well as the enhanced optical absorbance are the key factors for better performance of these ferroelectric semiconductors, which can be facilitated by depositing plasmonic Au nanoparticles on the surface of BiFeO<subscript>3</subscript>. As a result, the photoelectrochemical (PEC) and photovoltaic (PV) performance of BFO could be enhanced. We developed the BiFeO<subscript>3</subscript> nanostructures via a facile approach and then we have deposited Au nanoparticles on the surfaces of the BiFeO<subscript>3</subscript> nanoparticles. Electron microscopic images revealed the aggregation of 20–40 nm sized BiFeO<subscript>3</subscript> nanoparticles and the spherical shaped Au nanoparticles of ~ 30 nm. In addition to a noticeable enhancement in the optical spectrum, the plasmonic effect could be seen in the absorbance spectra after the decoration of Au nanoparticles. In order to assess the enhanced photovoltaic and photoelectrochemical performance of the Au-decorated BFO nanostructures, a comparative examination of pristine BFO was performed. Studies on the time-dependent photocurrent density also confirmed the stability of treated photoelectrode materials using Au nanoparticles. This really raised the charge transfer efficiency by delivering better conductivity, which was investigated using Nyquist plot. The incident photon-to-current conversion efficiency [IPCE(%)] also confirmed the enhancement of photovoltaic by Au nanoparticles. The DSSC efficiency of produced Au-decorated BiFeO<subscript>3</subscript> nanostructures is ~ 20% higher than the pristine BiFeO<subscript>3</subscript>-based cells. [ABSTRACT FROM AUTHOR]
