Abstract

Light soaking and hysteresis phenomena can reveal the bulk and interfacial polarization effects on photovoltaic processes in perovskite solar cells. The frequency‐dependent impedance and time‐dependent photoluminescence measurements indicate that bulk and interfacial polarizations are internally coupled in developing short‐circuit current, open‐circuit voltage, and fill factor through charge dissociation, transport, and collection in light soaking and hysteresis phenomena.
