DOI: 10.1002/adma.202207180
Abstract: The external quantum efficiency (EQE) of state‐of‐the‐art planar‐structure perovskite light‐emitting diodes (PeLEDs) is mainly limited by the outcoupling efficiency, which is around 20% and decreases significantly with the perovskite thickness. Here, an approach to artificially… read more here.
