Polarize the Solvent to Regulate the Intermediate Phase and Dynamic Crystallization of Perovskite Films

open access: yesAdvanced Materials, EarlyView.
A solvent engineering strategy using polar polymers is introduced to regulate perovskite crystallization dynamics in solar cells. Strongly polarized fluorinated groups stabilize the intermediate phase and control solvent exfoliation, leading to high‐quality films with suppressed defects.

CdTe Quantum Dots Encapsulated on Perovskite Grains Enable Highly Efficient and Stable Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Present work demonstrates an efficient laser‐assisted localized interfacial engineering strategy that achieves epitaxial‐grade atomic coherence in spatially defined p‐n microscopic heterointerfaces, via precisely embedding p‐type CdTe QDs into an n‐type perovskite matrix, which concurrently establishes dual optimization of microscale carrier management

On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions

open access: yesAdvanced Materials, EarlyView.
We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.

Tailored Nickel Oxide Interfacial Layers Unlock Enhanced Charge Dynamics in LaTiOxNy Thin Film Photoanodes

open access: yesAdvanced Materials Interfaces, EarlyView.
This study highlights the importance of designing photoanode architectures for solar water splitting that align intrinsic material properties with functional interfaces to optimize the extraction of photogenerated charges. The incorporation of NiOx surface layers in LaTiO2.5N0.5 (LTON) thin film photoanodes exemplifies this approach by leveraging band ...
