Multifactorial coupling to greatly enhance photocurrent density of BiFeO3-based ferroelectric photovoltaic architectures
The ferroelectric photovoltaic effect in BiFeO3 has attracted much attention recently. However, the potential of BiFeO3 as a photovoltaic material is limited due to its low photocurrent density and consequently low power conversion efficiency. Herein, a novel ferroelectric photovoltaic architecture based on the (Pr, Ni) gradient-doped BiFeO3-based thin film coupled with Au nanoparticles layer has been designed and fabricated. The experimental results and analysis show that this photovoltaic architecture exhibits extremely large photocurrent density (5.19 mA/cm2), which is about 472 times larger than that of pure BiFeO3 film (11 μA/cm2) and about 10 times larger than that of the conventional (Pr, Ni)-doped BiFeO3 film (0.54 mA/cm2). The enhanced photocurrent density should be attributed to the multifactorial coupling effect in this photovoltaic architecture, including the built-in electric field formed by the gradient distribution of oxygen vacancies, the flexoelectric effect and Local Surface Plasmon Resonance effect of Au nanoparticles.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
