A new ferroelectric photovoltaic materical with large polarization and suitable bandgap has been designed for using in photovoltaics. An excellent photovoltaic performance is achieved, i.e., a large photovoltage of 10 V and a photocurrent of 0.116 μA cm −2 . The direction of the photovoltage and photocurrent can be controlled by switching the direction of poling of the electric field, and the magnitude of the photovoltaic output can be tuned by adjusting the chemical composition.
