a τSRH of 1 ns and (b) 10 ns. The simulated transient E-field in the middle of perovskite bulk vs applied voltage compared with the corresponding hysteresis curves of (c) 0.1 V/s and (d) 10 V/s scan in (a). “Ref” refers to the reference device without mobile ion. e, f the position-dependent potential and bulk recombination profiles under a bias of 0.8 V, respectively.
