Anomalously bright single-molecule upconversion electroluminescence

open access: yes
Efficient upconversion electroluminescence is highly desirable for a broad range of optoelectronic applications, yet to date, it has been reported only for ensemble systems, while the upconversion electroluminescence efficiency remains very low for ...

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

open access: yesSolar 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

open access: yesAdvanced 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 ...

Adaptive automatic solar cell defect detection and classification based on absolute electroluminescence imaging

open access: yes
Current defect inspection methods for photovoltaic (PV) devices based on electroluminescence (EL) imaging technology lack juggling both labor-saving and in-depth understanding of defects, restricting the progress towards yield improvement and higher ...

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

open access: yesAdvanced 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.

Multimodal Bioinspired Self‐Healing Composites Enabling Durable and High‐Efficiency Wearable Perovskite Light‐Emitting Diodes

open access: yesAdvanced Science, Volume 13, Issue 61, 3 November 2026.
Butterfly wing–inspired intrinsically self‐healing polymer interlayers enable flexible perovskite optoelectronics with high luminance, strain‐insensitive stability, and environmental resilience. These hierarchically structured films redistribute mechanical stress, suppress defect formation, and maintain performance under repeated bending, paving the ...

Origin of Enhanced Efficiency and Reduced Roll‐Off in Organic Light‐Emitting Diodes Based on Pt(II) Complexes

open access: yesAdvanced Science, Volume 13, Issue 63, 12 November 2026.
Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...

Magnetic and Magneto‐Optical Techniques Elucidate Excited‐State Interactions in Mono‐ and Bis‐Substituted Helicenes

open access: yesChemPhotoChem, Volume 10, Issue 11, November 2026.
Here we demonstrate that the combination of magnetic circular dichroism (MCD) and time‐resolved electron paramagnetic resonance (TREPR) provides complementary insight into the singlet and triplet excited states of functionalized carbo[6]helicene. This approach is broadly applicable to both achiral and chiral molecules.

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

The application of electroluminescence imaging to detection the hidden defects in silicon solar cells

open access: yes, 2011
A method of using electroluminescence (EL) imaging to detect the hidden defects in silicon solar cells under the condition of certain bias is presented in this paper. The EL wavelength of silicon solar cells ranges from 850 nm to 1200 nm.
