The photovoltaic effect of the heterojunction based on multiferroic material BiFeO 3 and organic semiconductor poly(3‐hexylthiophene) has been studied for the first time. A typical rectifying J–V characteristic of the heterojunction is observed with a rectifying ratio of ∼10 3 . The power conversion efficiency of the device is comparable to those of hybrid solar cells based on poly(3‐hexylthiophene) and other oxide semiconductors, such as TiO 2 or ZnO, indicating that BiFeO 3 is a promising material for photovoltaic devices.
