AbstractWe investigated the influence of two passivating moleculescontaininga P=O group on the performance of quasi-2D Dion-Jacobsonhalide perovskite light-emitting diodes, namely, triphenylphosphineoxide (TPPO) and diphenyl-4-triphenylsilylphenyl phosphine oxide (TSPO1).We found that both passivating molecules lead to increased efficiencycompared to control devices, while they had opposite effects on devicelifetime, with a decrease observed for TPPO and an increase observedfor TSPO1. The two passivating molecules resulted in differences inenergy-level alignment, electron injection, film morphology and crystallinity,and ion migration during operation. While TPPO resulted in mproved photoluminescence decay times, overall higher maximum external quantumefficiency (EQE) and device lifetime were obtained for TSPO1 comparedto TPPO (14.4% vs 12.4% EQE, 341 min vs 42 min T-50).
