Efficient Rec. 2020 Compliant Pure‐Green Mixed‐Cation Perovskite Light‐Emitting Diodes With Multifunctional Co‐Additives

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: May 13, 2025

Abstract Perovskite light‐emitting diodes (PeLEDs) compliant with Rec. 2020 standards have raised increasing attention for next‐generation displays. As a class of pure‐green emitters, the mixed‐cation FA x Cs 1‐x PbBr 3 perovskites exhibit compatible band emission, but suffer from inferior luminescence performance. The approach to tackling this issue is hindered by lack in‐depth understanding their crystallization manipulating mechanism. This work unveils process 0.7 0.45 GA 0.1 perovskites, demonstrating fast spontaneous growth readily induces severe crystal defects accompanied poor charge confinement. motivates us introduce additional kinetic barriers manipulate perovskite via synergistic co‐additives 3‐((2‐(methacryloyloxy)ethyldimethyl)ammonio)‐propane‐1‐sulfonate (DMAPS) and 1,4,7,10,13,16‐hexaoxacyclooctadecane (crown). multifunctional groups in afford robust chemical affinities diverse organic inorganic precursor ions simultaneously, which enable decent nanograin effective defect healing Ultimately, high photoluminescence quantum yield 96% are achieved. resultant PeLEDs compliance champion external efficiency (EQE) 31.89%, average EQE 29.5%, maximum luminance 2 × 10 5 cd m −2 operational half‐lifetime 3.2 h at an initial 7000 (extrapolated: ≈3500 100 ).
