Organometal halide perovskite-based solar cells have shown rapid improvement in their performance.

State-of-the-art solar cell technologies, such as hetero-junction cells or PERC cells, exhibit a time-dependent deformation of their current-voltage characteristics in fast solar simulator measurements.

Hysteresis behavior is a unique and significant feature of perovskite solar cells (PSCs), which is due to the slow dynamics of mobile ions inside the perovskite film 1, 2, 3, 4, 5, 6, 7, 8, 9. It yields uncertain current density-voltage (J–V) curves of the cells depending on the voltage scan protocols.
