Characterize and Retard the Impact of the Bias-Induced Mobile Ions in CH3NH3PbBr3 Perovskite Light-Emitting Diodes

Teng Lam Shen et al.

Summary: This study reports on the ion migration in polycrystalline CH3NH3PbBr3 thin film and its significant impact on the output performance of perovskite light-emitting diodes (PeLEDs). Adding the Choline chloride molecule in the precursor solution effectively interferes with ion migration in PeLEDs, leading to stable EL and LE. Suppressing the influence of migrating ions is crucial for advancing the efficiencies and operational stabilities of perovskite devices.

Summary: In this study, highly efficient large-area PeLEDs with high uniformity were achieved through the use of colloidal perovskite nanocrystals. The precrystallized PNCs were not affected by the film formation process and a modified bar-coating method facilitated the formation of uniform large-area films. This method shows promise for the development of large-scale industrial displays and solid-state lighting.

Highly Efficient Vacuum-Evaporated CsPbBr3 Perovskite Light-Emitting Diodes with an Electrical Conductivity Enhanced PolymerAssisted Passivation Layer

Nakyung Kim et al.

Summary: Efficient vacuum-deposited CsPbBr3 perovskite light emitting diodes (PeLEDs) are achieved by introducing a separate polyethylene oxide (PEO) passivation layer. The enhancement in photoluminescence quantum yield intensity is attributed to the passivation of interfacial defects of the perovskite by the PEO layer. Doping PEO layers with MgCl2 solves the issue of PEO's electrically insulating nature, resulting in enhanced luminance and external quantum efficiency (EQE).
