Synergistic Additive and Bulky Cation Engineering via a Sequential Vacuum Dry‐Dipping Process for Tin Perovskite Solar Cells

Advanced Science, EarlyView.
A spin‐coating‐free sequential blade–dipping process is developed for efficient tin perovskite solar cells. Amorphous SnI2 templates are blade‐coated and vacuum‐dried, followed by a vertical dipping conversion. Enhanced by a synergistic additive matrix and bifunctional BATo cation, the resulting devices achieve a benchmark power conversion efficiency ...

Organometal halide perovskite as hole injection enhancer in organic light-emitting diode

, 2017
We introduce an organometal halide perovskite (CH3NH3PbI3), as a hole injection layer (HIL) to accelerate hole injection and transport in tris-(8-hydroxyquinoline) aluminum-based organic light-emitting diodes (OLEDs).

Engineering Large‐Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High‐Performance, Ultralow‐Noise Perovskite Photodetectors

Advanced Science, EarlyView.
Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...

Van der Waals Heterostructures for Next‐Generation Spintronics: Multiferroic‐Mediated Magnetoelectric Properties

Advanced Science, EarlyView.
As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.
