Exemplified scan rate-dependent J–V curves after 480 min of ageing. The steady-state and ion-freeze PCE are defined at slow and fast scan speeds at which the hysteresis disappears, respectively. This is exemplified by the dashed horizontal lines at 480 min of ageing for the PCE and J SC in a and b , respectively. The peak hysteresis shows the maximum difference between the forward and reverse scan PCE as exemplified by the vertical arrow at 480 min of ageing.
