A Mixed Organic-Inorganic Interlayer with Tunable Electrical Properties Enabling Stable and Efficient Perovskite Light-Emitting Diodes

The operational stability of perovskite light-emitting diodes (PeLEDs) is subjected to undesired Joule heating induced by the charge imbalance and the current leakage. The hole injection efficiency is inferior to that of electrons in the electron-dominated PeLEDs, owing to the low hole mobility of h...
