High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Harnessing Self‐Sensitized Scintillation by Supramolecular Engineering of CsPbBr3 Nanocrystals in Dense Mesoporous Template Nanospheres

open access: yesAdvanced Materials, EarlyView.
Perovskite CsPbBr3 nanocrystals exhibit bright emission, fast response, and solution processability, but their nanoscale size limits efficient radiation detection. Organizing them into porous SiO2 mesospheres enhances radioluminescence up to 40 times, achieving an optimal combination of light yield, fast scintillation, and processability, providing a ...

A Lightweight, Flexible and Mechanically Robust Nonwoven Copper Metallized Nylon‐6 Fibers for Enhanced Charge Dissipation and Reduced Electrical Resistance for ESD Protection

open access: yesAdvanced Materials Interfaces, EarlyView.
A breathable and mechanically robust PA6 electrospun textile is modified via physical vapor deposition of a nanoscale copper layer, enabling efficient electrostatic charge dissipation. The resulting material exhibits a 99.6% decrease in triboelectric voltage and a 60% increase in tensile strength, offering a multifunctional solution for electrostatic ...

Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining

open access: yesAdvanced Materials Technologies, EarlyView.
Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.
