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

Advanced 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 ...

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Ion‑Mediated Structural Engineering of Hydrogel Interfaces for Tunable Mechanical and Analyte Diffusion Properties in Electrochemical Biosensors

Advanced Materials, EarlyView.
An ion‐mediated structural engineering strategy enables versatile modulation of PVA–Alginate hydrogel microstructure. We systematically examine how different ion combinations affect hydrogel mechanical properties and analyte diffusivity. Applying this novel strategy to hydrogel as the outer membrane in an electrochemical glucose biosensor allows ...

Electrically Assisted Thermal Stamping of Tunable Carbon‐Based Nanofilms for Direct Fabrication of Hydrophobic, Energy Harvesting, and Sensing Devices

Advanced Materials, EarlyView.
Schematic illustration of the electrically assisted thermal stamping (EATS) method for direct fabrication of carbon‐based nanofilms and their multifunctional applications. Localized Joule heating triggers simultaneous exfoliation, reduction, and fluoropolymer incorporation under ambient conditions, yielding tunable carbon‐based thin‐film coatings ...

Impact of Nano‐Scale Defects on the Macroscopic Amplified Spontaneous Emission in Polycrystalline Perovskite Thin‐Films

Advanced Materials, EarlyView.
In this work, we discovered that optical gain within these polycrystalline perovskite thin films occurs primarily at defective sites, where, despite the low photoluminescence efficiency, we demonstrated high optical gain efficiency and long photocarrier lifetime. Our findings highlight the importance of defects in the development of electrically pumped

Hybrid Liquid Metal Cathode Enables High‐Performance Intrinsically Stretchable OLEDs

Advanced Materials, EarlyView.
We report a hybrid liquid metal (Hyb‐LM) cathode engineered via selective rupture of liquid metal particles (LMPs), forming a bilayer architecture with a surface liquid metal (LM) layer and underlying LMP layer, which has benefits of both LM and LMPs.
