READ MOREWe dramatically increased the ferroelectric photovoltaic effect to ∼135.67 μA/cm 2 from 30.62 μA/cm 2, which is the highest in ferroelectric thin films with a thickness of less than 100 nm under white-light LED irradiation. More importantly, the ferroelectric polarization can effectively improve the photovoltaic efficiency of more than 5 times.
