Shuming Chen and co‐workers develop inverted tandem quantum dot light‐emitting diodes (QLEDs) with efficiencies of over 100 cd A −1 . The devices described in article number 1700610 use PEDOT:PSS/ZnMgO as the inter‐connecting layer (ICL) and reach efficiencies comparable with those of phosphorescent OLEDs. The results demonstrate an ICL and fabrication methods that are able to boost the performances of QLEDs.
