"Greatly enhanced photocurrent density in bismuth ferrite films by Loca" by Yunpeng Li, Jie Wei et al.
Very recently, the ferroelectric photovoltaic effect of multiferroic BiFeO3 (BFO) has attracted much attention because of its large photovoltage beyond the bandgap and unique photocurrent switchable characteristics. However, the poor short-circuit current density (JSC ∼ μA/cm2) of BFO leads to a low power conversion efficiency (PCE), which greatly hinders its application and development as photovoltaic or optoelectronic devices. In this paper, a novel heterostructure comprised Au nanoparticles layer and BiFe0.9375Mn0.0625O3 (BFMO) thin film was constructed. The results and analysis showed t...
