“Understanding and Overcoming the Poor Efficiency of QLEDs Utilizing Organic Electron Transport Layers”

open access: yesAdvanced Electronic Materials, Volume 11, Issue 18, November 4, 2025.
Contrary to expectations, the electron is identified as a leakage that plays a leading role in limiting the efficiency of QLEDs with organic ETLs. By using a multilayer ETL configuration that includes electron blocking interfaces, electron leakage can be reduced and EQE substantially increased, reaching 10%, the highest for a green QLED with an ...
