When mixed ionic-electronic conductors are used in optoelectronic devices. Ionic effects in perovskitesolar cells are believed to be distorted. Current hysteresis and switchable photovoltaic characteristics have been linked to the kinetics of ion migration. However, the nature of the specific ionic mechanism (or mechanisms) can not be understood. It is considered that the local rearrangement of the electrode interfaces gives rise to a high degree of apparent capacitive effects. CH3NH3PbI3 samples show two main polarization processes and reveal the structure of the ionic double-layer at the interface with the non-reacting contacts. It is observed that the ionic charging, with a typical response time of 10 seconds, is a local effect confined in the vicinity of the electrode, which entails absence of net mobile ionic concentration (space-charge) in the material bulk.
