Accelerated Development of Vapor Deposition Technology for Efficient Perovskite Solar Cells via Accurate and Practical Machine Learning Tools

Advanced Science, EarlyView.
Based on rational feature selection, an integrated‐feature dataset is constructed encompassing macro‐ and micro‐feature parameters. Screening and optimization across ten algorithmic models enhanced predictive accuracy and robustness for power conversion efficiency (PCE), yielding an R2 of 0.9464 and RMSE of 1.27%.

Ultrafast Photoexcitation Induced Nonthermal Lattice Expansion in 2D Perovskite

Advanced Science, EarlyView.
Photo‐induced lattice expansion in 2D Dion‐Jacobson (DJ) perovskites is a non‐thermal process, resulting in the more relaxed local lattice strain and the larger bandgap. It activates a self‐passivation mechanism, effectively diminishing trap state density. The synergy of these effects leads to suppressed non‐radiative recombination and prolonged charge

Lead‐Free Tin‐Based Perovskite LEDs Toward Rec. 2020: Organic Anion Coordination for Oxidation Suppression

Advanced Science, EarlyView.
This study introduces an organic anion‐coordination for oxidation suppression (OCOS) strategy using alkali metal–organic anions (e.g., KEtO) to stabilize Sn2+ in lead‐free Sn‐based perovskites for PeLEDs. By coordinating with Sn2+ and inhibiting vacancies, OCOS enhances film quality, EQE (to 10.01% at 638 nm), and luminance (to 139.9 cd m−2 ...

Partial Reprogramming in Senescent Schwann Cells Enhances Peripheral Nerve Regeneration via Restoration of Stress Granule Homeostasis

Advanced Science, EarlyView.
In this study, it is discovered that pathological accumulation of Runx2+ Schwann cell clusters​ during axonal regeneration is a key factor impairing nerve repair in aging. This pathology is associated with ​dysregulation of stress granule homeostasis.

Unravel the Effects of UV Light on the Lattice Stability of Perovskite via Numerical Simulation

Advanced Science, EarlyView.
The perovskite lattice stability against UV light is enhanced via appropriate doping and additive strategies, which promotes their future applications in (near) space environments. Abstract The light degradation of perovskite greatly hinders the commercialization of perovskite solar cells, which is yet to be resolved, despite the many attempts.

Engineered Multifunctional Hydrogel Delivering Novel CBX7 Inhibitor Modulates Cuproptosis Via Liquid–Liquid Phase Separation to Restore Cardiac Function in Aged Myocardial Infarction

Advanced Science, EarlyView.
An age‐adapted therapy pairs δ‐Amyrenone, a CBX7 inhibitor, with an alginate hydrogel (CSAδ) to rescue infarcted elderly hearts. CSAδ disrupts CBX7–ATP7A liquid–liquid phase separation, restores ATP7A trafficking and copper efflux, suppresses cuproptosis, supplies oxygen, scavenges ROS, promotes M2 polarization, supports angiogenesis, and enhances ...

Solid Additives for Spontaneously Spreading‐Processed Organic Photovoltaics

Advanced Science, EarlyView.
This work developed a spontaneous spreading process with solid additives for the fabrication of organic photovoltaics (OPVs). By regulating interfacial tension, the solid additives enable the formation of uniform films on the water surface. A remarkable power conversion efficiency of 16.4% is recorded in the OPVs using phenanthrene (PAT) as the ...
