Abstract
A defect-engineering strategy is reported to enhance the photovoltaic performance of BiNbO<sub>4</sub>. Synergetic effects: enhanced light absorption, ferroelectric-like depolarization and interfacial polarization on BiNbO<sub>4</sub> homojunction lead to an increase in the photovoltaic effects.
