High-Performance Planar Perovskite Light Emitting Diodes: Morphological and Interfacial Control via a Polar Solvent Treatment |
| 초록 |
Organic-inorganic hybrid perovskite materials have been extensively researched because of their amenability to solution-based processing; their superior electrical properties, high carrier mobility; and the ability to tune their optical bandgaps. The ability to achieve a perovskite layer with a uniform morphology, high crystallinity and charge-selective behaviour through interfacial engineering is critical. Here, we enhance the efficiencies of conventional structured planar perovskite light-emitting diodes (LEDs) by applying a polar solvent treatment to compact TiO2 and optimising the morphology of the perovskite layers because of enhancement of electron injection. Moreover, a uniform and dense perovskite layer with full surface coverage was realised using adequate solvent, and nearly full coverage of green electroluminescence through the highly uniform morphology of the perovskite layer was observed in conventional planar perovskite LEDs. |
