Quantum dots light‐emitting diodes (QLEDs) have attracted much interest owing to their compatibility with low‐cost inkjet printing technology and potential for use in large‐area full‐color pixelated display. However, it is challenging to fabricate high efficiency inkjet‐printed QLEDs because of the coffee ring effects and inferior resistance to solvents from the underlying polymer film during the...
In article number 1900111, Wenming Su and co‐workers synthesize a crosslinkable hole transport material, 4,4′‐bis(3‐vinyl‐9H‐carbazol‐9‐yl)‐1,1′‐biphenyl (CBP‐V) for inkjet printing of quantum dots light‐emitting diodes (QLEDs). The inkjet‐printed CBP‐V film is smooth and flat. After thermal curing, an extremely dense and crosslinked solvent resistant film is formed. The function of this film for...
Large‐scale fabrication of organic solar cells requires an active layer with high thickness tolerability and the use of environment‐friendly solvents. Thick films with high‐performance can be achieved via a ternary strategy studied herein. The ternary system consists of one polymer donor, one small molecule donor, and one fullerene acceptor. The small molecule enhances the crystallinity and face‐on...
