Morphological Stabilization of CsPbBr3 Quantum Dot Films Enabled by PVC‐g‐PMMA Graft Copolymer Encapsulation for Water‐Robust Color Conversion

Small, EarlyView.
Poly(vinyl chloride)‐graft‐poly(methyl methacrylate) encapsulation enabled formation of water‐stable CsPbBr3‐quantum‐dot fims with enhanced photoluminescence (PL) retention upon exposure to water, UV radiation, and ethanol. Time‐dependent ex situ transmission electron microscopy with quantitative particle segmentation identified the coefficient of ...

Enhanced Efficiency and Thermal Stability in All‐Polymer p‐i‐n Organic Photovoltaics With Synergistically Designed Second Polymer Acceptor

Small, EarlyView.
Incorporation of a synergistic selenophene‐substituted acceptor, PYISe‐BO‐OD into PYIT‐OD, enabled PM6/PYIT‐OD:PYISe‐BO‐OD all‐polymer p‐i‐n organic photovoltaics with PCE and T80 value of 19.1% and 3415 h, substantially outperforming PM6/PYIT‐OD devices (16.3%, 937 h).

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Scanning tunnelling luminescence at the single molecule limit: A perspective

Journal of Microscopy, EarlyView.
Abstract Scanning tunnelling microscope‐induced luminescence (STML) is transforming scanning probe microscopy from a tool that images and manipulates matter into one that directly probes the excited‐state dynamics governing chemistry at the single‐molecule level.

AI‐Based PV Fault Detection: Benchmarking Indicators and Feature Selection Methods

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 12, Page 1603-1616, December 2026.
This article benchmarks indicators for automated defect detection in photovoltaic modules. The methodology has three phases: generating a simulated ideal defect‐free I‐V curve, comparing it with experimental measurements under standard test conditions, calculating indicators, and applying a feature‐selection strategy to identify the most relevant ...

Identification of Local Performance Losses in Perovskite Solar Cells Through Coupled Luminescence Imaging and Physics‐Based Statistical Modelling

Solar RRL, Volume 10, Issue 21, 16 November 2026.
Coupled photoluminescence and electroluminescence imaging with multiphysics‐based statistical modelling enables quantitative diagnosis of local performance losses in perovskite solar cells. The approach identifies the physical origins of nonuniformities by distinguishing loss mechanisms and extracting the underlying physical parameters, transforming ...

Out‐of‐Plane Strain‐Decoupled Architecture for High‐Fill‐Factor Stretchable OLED Displays

Advanced Functional Materials, Volume 36, Issue 88, 2 November 2026.
A vertically decoupled multilayer SOLED architecture separates emissive pixel islands from deformable interconnects, allowing low‐modulus elastomeric layers to accommodate applied strain and suppress strain transfer to the OLED region. This design, combined with transparent hybrid encapsulation, enables a high fill factor (∼75%), stretchability ...

Halide Composition Controls Phase Morphology and Device Specific Performance in Perovskite Photovoltaics and Light Emitting Diodes

Advanced Functional Materials, Volume 36, Issue 90, 9 November 2026.
We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

Fluorene‐Framework Engineering Enables Narrowband Red Multi‐Resonance Emitters for High‐Efficiency With Negligible Roll‐Off Toward BT.2020

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
σ‐Decoupled C9 fluorene‐framework topology control enables narrowband red MR emitters. SF‐BNO and PF‐BNO share the same BNO core, but differ in closed/open fluorene ring closure. SF‐BNO improves steric shielding and stability, while PF‐BNO enhances PLQY, orientation, and efficiency. Ex‐PSF and TE‐OLED architectures deliver ultra‐low efficiency roll‐off
