Figure 1

Characterization of perovskite LEDs without or with Tween-TPPB additives: (a) device structure; (b) composition of the emitting layer; (c) PL and EL spectra; (d) current density and luminance versus voltage; (e) EQE versus current density; (f) EL spectra upon various voltages of the Tween-TPPB-based device. Inset: photograph of the device.
