In this direction bismuth ferrite has shown a great potential since a large photocurrent effect and above bandgap voltage is observed in this material under illumination. Most of the works using bismuth ferrite as a photovoltaic material has been reported on its thin film form but in a few reports researchers have formed a bilayer structure with other materials like polymers, graphene and other semiconductors. In a report p-i-n heterojunction has been formed with bismuth ferrite nanoparticles along with two oxide based carrier transporting layers.
Bismuth ferrite has shown promise as a photovoltaic material due to its large photocurrent effect and above bandgap voltage under illumination, particularly when used in thin films or bilayer structures with other materials like polymers, graphene, or semiconductors. A p-i-n heterojunction was recently formed using bismuth ferrite nanoparticles alongside two oxide layers for enhanced carrier transport.
