Abstract

Researchers systematically studied the structural change of CH3NH3PbBr3 from bulk film to layered perovskite film and established structure-property relationship of the hybrid perovskite system. The different perovskite films were then applied as emissive layer to fabricate perovskite LEDs. They have found that the device performance is strongly dependent on the perovskite film structure, and efficient and relatively stable blue and green LEDs were demonstrated under optimized structures. The CH3NH3PbBr3 perovskite structure was tuned by adding different amount of 2-phenoxyethylamine (POEA) into CH3NH3PbBr3 precursor solution. The final structure of the hybrid perovskite has been determined by two factors, including the molecular interactions and molecular ratio between the added molecule and the perovskite crystal.
