Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Unified Analytical Framework for Understanding the Operational Stability of Blue Phosphorescent OLEDs: Quantitative Insights Into Exciton Recycling and Bimolecular Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.

Advancing Tandem Organic Solar Cells With Ternary Acceptor Control for High‐Power Modules and Solar‐to‐Ammonia Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Tandem organic solar cells with optimized ternary acceptor engineering achieved a power conversion efficiency of 15.53% and enabled a high‐voltage mini‐module (Voc 6.11 V). Integration into a bias‐free PV‐EC system further demonstrated efficient solar‐to‐ammonia (STA) conversion (97% Faradaic Efficiency, 4± 2% STA efficiency), highlighting scalable ...

Evaluation of spectroscopic ellipsometry from ultraviolet–visible–(near-infrared) to terahertz regions for the analysis of silicon photodiodes [PDF]

open access: yesAIP Advances
Spectroscopic ellipsometry (SE) has been evaluated for the analysis of silicon photodiodes (PDs), employing instruments spanning the spectral regions of the ultraviolet-to-near-infrared (UV–Vis–NIR: 0.75–5.90 eV), near-infrared-to-mid-infrared (NIR–Mid ...

Coaxially Electrospun Myocardial dECM‐ Based Nanofibrous Scaffolds Demonstrate Enhanced Cardiomyocyte Biocompatibility

open access: yesAdvanced Healthcare Materials, EarlyView.
Our coaxial electrospinning system is capable of incorporating decellularized myocardial extracellular matrix in a core‐sheath configuration, creating nanofibrous scaffolds. These scaffolds, in turn, support the maintenance of functional cardiomyocytes adhered to the surface of these bioactive scaffolds.

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration

open access: yesAdvanced Healthcare Materials, EarlyView.
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic
