Perovskite light‐emitting diodes (PeLEDs) have shown incalculable application potential in the fields of next‐generation displays and light communication owing to the rapidly increased external quantum efficiencies (EQEs). However, most PeLEDs obtain a maximum EQE at small current density (J) region and suffer from severe efficiency roll‐off in different extents. Herein, it is demonstrated that the...
Hole‐transport‐layer‐free (HTL‐free) perovskite light‐emitting diodes (PeLEDs) are attracting increasing research attention because of their simplified device structure, fast preparation process, and high cost effectiveness. However, their much lower external quantum efficiency (EQE) as compared with the conventional p‐i‐n type ones has considerably limited their application prospects. Here, a self‐assembled...
Challenges remain hindering the performance and stability of inverted perovskite solar cells (PSCs), particularly for the nonstable interface between lead halide perovskite and charge extraction metal oxide layer. Herein, a simple yet scalable interfacial strategy to facilitate the assemble of high‐performance inverted PSCs and scale‐up modules is reported. The hybrid interfacial layer containing...
Vacuum vapor deposition (VVD) is a promising way to advancing the commercialization of perovskite light sources owing to its convenience for wafer‐scale mass production and compatibility with silicon photonics manufacturing infrastructure. However, the light emission performance of VVD‐grown perovskites still lags far behind that of the conventional solution‐processed counterparts due to their inferior...
