[OLED3/PH3-1(Invited)] High Efficiency and Durability from Perovskite–Organic Hybrid Light-Emitting Diodes
metal halide perovskite, organic, light-emitting diode, efficiency
We show that triplet excitons are key to efficient emission in quasi-2D perovskite devices and that quenching of triplets by the organic cation is a major loss path. Employing an organic cation with a high triplet energy level in a quasi-2D perovskite yields efficient harvesting of triplets.
