Blue Perovskite LEDs: Reducing Architecture Limitations for Efficient Blue Perovskite Light‐Emitting Diodes (Adv. Mater. 20/2018)

Blue perovskite light‐emitting diodes (LEDs) have lagged significantly behind red and green ones. In article number 1706226 , Daniel N. Congreve and co‐workers show that the device architecture plays a key role in this lag, and they propose an alternate structure that maintains robust ...
