The electrical property of perovskite is controlled by its crystalline structure and compositions. It has shown that the hysteresis in perovskite solar cells is not only due to one mechanism. However, numerous factors lead to hystereses such as ferroelectricity, ion migration, charge trapping, and capacitive effects.
Hysteresis has a detrimental influence on the reliability of photovoltaic operation and long term stability of hybrid perovskite solar cells. Owing to its complex structure, it is not easy to attribute the hysteretic behavior to any one of different components, such as the bulk of the perovskite or different heterojunction interfaces.
Various strategies to alleviate the J–V hysteresis in perovskite solar cells are summarized. Insights into hysteresis-free device are proposed. Organic-inorganic hybrid perovskite solar cell (PSC) has received widespread attention due to its high efficiency, low cost, and easy fabrication process.
Snaith et al. proposed that the specific device architecture is highly influential to the severity of the anomalous hysteresis present in the current–voltage characteristics of perovskite solar cells .
Though numerous theories have been proposed to explain the causes of hysteresis, its origin includes slow transient capacitive current, trapping, and de-trapping process, ion migrations, and ferroelectric polarization. The remaining issues and future research required toward the understanding of hysteresis in PSC device is also discussed.
