Oriented Crystallization of Perovskite Film via Fluorine‐Containing Hyperbranched Polymer for Efficient and Stable Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
A fluorine‐containing hyperbranched polymer is developed to guide oriented crystallization and construct a cross‐linked hydrophobic network, enabling the formation of high‐quality perovskite films with enhanced environmental stability. The resulting devices deliver a PCE of 26.05% (0.04 cm2) and 22.43% (16.1 cm2), while maintaining 97% of their initial

Lithographically Controlled Liquid Metal Diffusion in Graphene: Fabrication and Magnetotransport Signatures of Superconductivity

open access: yesAdvanced Materials, EarlyView.
Lithography‐guided intercalation creates a proximitized 2D superconducting Ga layer under graphene Hall bars via liquid‐metal intercalation. The image shows a Hall bar where Ga atoms from the liquid phase enter through patterned intercalation channels beneath quasi‐freestanding bilayer graphene, forming a confined 2D metal that demonstrates ...

Bifunctionally Driven Organic Photonic Conversion Devices Facilitated by Minimalistic Synthesis‐Based Interfacial Energetic Alignment

open access: yesAdvanced Materials, EarlyView.
A benzene‐phosphonic acid self‐assembled monolayer (BPA) simultaneously optimizes hole extraction and noise suppression, enabling bifunctional organic photovoltaics–photodetectors that deliver superb indoor performance and commercial viability. BPA‐devices achieve 28.6% PCE at 1000 lx, retain 93% efficiency on large‐scaled devices, and reach 584 fW NEP

Acidity‐Mediated Metal Oxide Heterointerfaces: Roles of Substrates and Surface Modification

open access: yesAdvanced Materials, EarlyView.
The role of local space charge, not only at heterointerfaces, but also at grain boundaries, influenced by surface acidity modulation is elucidated through model platforms composed of Pr‐doped ceria (mixed ionic‐electronic conducting oxide) nanowire arrays.
