Description:

This study demonstrates a high-efficiency, high-color-purity hybrid tandem (h-tandem) perovskite light-emitting diode (PeLED) that combines PeLED and organic light-emitting diode (OLED) units. Through microcavity optimization (h-Tandem Valley) and near-perfect charge balance, the device achieves an EQE of 37.0% and an FWHM of 27.3 nm, showcasing its potential for next-generation displays with superior performance and color purity.
