This document summarizes recent advances in understanding the photovoltaic effect in ferroelectric (FE) materials. It discusses several theories that aim to explain the origin of the FE photovoltaic effect, including the shift current model, non-linear dielectric model, domain wall theory, Schottky junction effect, and depolarization field model. It also reviews factors that influence the measured photovoltage in FE materials and discusses progress integrating FE materials into organic photovoltaic devices to help with charge separation. While clarification is still needed on distinguishing between intrinsic and extrinsic contributions to the photovoltage, this document provides a useful overview of the current state of research into utilizing the FE effect for photovoltaics.
