Pulsed Operation of Perovskite LEDs: A Study on the Role of Mobile Ions

Caption

Figure 1: Simulated (a)-(c) and experimental (d)-(f) TrEL results for a 1 kHz signal with varying duty cycles. (a) First simulated pulse, starting from rest. (b) Simulated TrEL signals for converged-state pulse after 0.2 seconds (200th pulse). (c) Simulated overshoot with normalized plateau value for 200th pulse. (d) Experimental low temperature TrEL signal measured at 175 K and 3.5 V. (e) Experimental TrEL signal at 1.7 V measured at room temperature. (f) Experimental overshoot with normalized plateau value.
