Data‐Driven Analysis of Transparency–Efficiency Trade–Offs and Indoor Spectral Matching in Perovskite Photovoltaics

open access: yesSolar RRL, Volume 10, Issue 18, 28 September 2026.
A curated analysis of semitransparent and indoor perovskite PVs reveals how transparency, efficiency, and spectral matching interact under realistic illumination. The study defines an empirical performance envelope and shows that efficient transparent devices must balance optical transmission with spectrally matched absorbers and minimized interface ...

Decoupling Transparency and Electron Injection in Ultrathin Ag Electrodes Using an Al/MoO3 Double Seed Layer for Transparent Quantum Dot Light‐Emitting Diodes

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
Transparent quantum dot light‐emitting diodes (Tr‐QLEDs) employing an Al/MoO3 double seed layer decouple optical transparency from electron injection in ultrathin Ag electrodes. The functionally separated seed layers enable low optical loss and efficient charge injection simultaneously, resulting in improved electroluminescent performance, enhanced ...

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots

open access: yesAdvanced Functional Materials, Volume 36, Issue 73, 10 September 2026.
CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

Direct Integration of Conductive, Emissive Perovskite Nanocrystals Into Efficient Light‐Emitting Diodes Without Post‐Synthetic Ligand Exchange

open access: yesAdvanced Functional Materials, Volume 36, Issue 75, 17 September 2026.
We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge

Single-photon characterization by two-photon spectral interferometry

open access: yes, 2019
Single-photon sources are a fundamental resource in quantum optics. The indistinguishability and purity of photons emitted from different sources are crucial (necessary, essential) properties for many quantum applications to ensure high-visibility ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Asymmetric Lamellar Templating of the Perovskite/C60 Interface for Scalable Inverted Perovskite Photovoltaics

open access: yesAdvanced Materials, Volume 38, Issue 53, 21 September 2026.
Asymmetric lamellar templating at the perovskite/C60 interface is achieved using a laterally polarized indole spacer. Surface anchoring and Ind–Ind assembly form a π‐rich lamellar interphase that supports uniform C60 contact formation, suppresses recombination, preserves electron extraction, and enables certified high‐efficiency cells and modules with ...
