Homogenous FACsPbI3 Perovskite Solar Cells Enabled by a Seed‐Facilitated Cation Exchange Strategy

Advanced Functional Materials, EarlyView.
A novel seed‐facilitated cation exchange strategy is designed for homogenous FACsPbI3 perovskites using the biomass‐derived solvent γ‐valerolactone. Pre‐deposited 0D Cs4PbI6 seeds induce rapid nucleation and efficient cation exchange, producing a uniform FA–Cs distribution and significantly reducing defect density, enabling high‐performance and stable ...

Rationally Designed Bilayer Passivation Strategy for High‐Performance Vacuum‐Processed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

Solvent Co‐Intercalation Enabled Ca Storage in MoS2 for Ca‐Ion Batteries

Advanced Functional Materials, EarlyView.
Regulating electrolyte solvation levels enables otherwise non‐intercalatable Ca2+ ions to reversibly co‐intercalate into molybdenum disulfide (MoS2) as ether‐solvated species. The intercalation reversibility is strongly governed by solvent chain length, as demonstrated using diethylene glycol dimethyl ether (G2) and tetraethylene glycol dimethyl ether (

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, EarlyView.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...

Robust edge photocurrent response on layered type II Weyl semimetal WTe2

Nature Communications, 2019
Novel optoelectronic properties have recently been observed in topological semimetals. Here, Wang et al. report a robust photocurrent generated from charge separation of photoexcited electron-hole pairs at the edge of a type-II Weyl semimetal, T d-WTe2.

Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN

Advanced Functional Materials, EarlyView.
Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...
