The Deepest Blue: Major Advances and Challenges in Deep Blue Emitting Quasi‐2D and Nanocrystalline Perovskite LEDs

Advanced Materials, EarlyView.
In this review, the recent development of deep‐blue (≤465 nm) perovskite light‐emitting diodes (PeLEDs) are summarized, using different perovskite nanomaterials, including nanocrystals (NCs), quantum dots (QDs), nanoplatelets (NPLs), quasi‐2D thin film, 3D bulk thin film, as well as lead‐free perovskite nanomaterials.

Molecular Control of the Donor/Acceptor Interface Suppresses Charge Recombination Enabling High‐Efficiency Single‐Component Organic Solar Cells

Advanced Materials, EarlyView.
The outstanding double‐cable‐based single‐component material, DCPY2, exhibits a suppressed charge recombination process alongside efficient charge generation. This results in a high fill factor and short‐circuit current, yielding an efficiency to 13.85%.
