Nanoscale Rear‐Interface Architecture Enables 36.2 mA cm−2 Photocurrent in Ultrathin and Bifacial ACIGS Solar Cells Through Light Management

Laser &Photonics Reviews, EarlyView.
An array of SiOx nanopillars is developed on ITO transparent rear contacts through nanoimprint lithography to promote light scattering in 500–600 nm bifacial ACIGS solar cells. This architecture increases the short‐circuit current density by 7.8 and 7.6 mA cm−2 under front (up to 36.2 mA cm−2) and rear illumination, respectively, offering a scalable ...

Effect of organic additives on mechanical properties of SiC ceramics prepared by a modified gelcasting method [PDF]

Processing and Application of Ceramics, 2016
A novel and simple gel system of isobutylene and maleic anhydride (PIBM) was used to prepare SiC ceramics. The rheological behaviour of the SiC slurries was investigated as function of organic additives.

Unraveling the Proton‐Induced Degradation Mechanism in Quantum‐Dots Light‐Emitting Diode for Space Applications

Small, EarlyView.
Low‐energy proton irradiation induces ligand detachment at the QD/ZnO interface in quantum‐dot light‐emitting diodes (QLEDs). The exposed ZnS surface interacts with ZnO defects, generating a high density of interfacial trap states that promote electron trapping, suppress charge injection, and accelerate non‐radiative recombination, ultimately leading ...

Translocated Clam Retention and Effects on Ecosystem Functions Across a Gradient of Environmental Stress

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.
Estuarine ecosystems are experiencing increasing land‐derived stress, bringing sediments, excess nutrients and contaminants. Once degraded, disturbed soft sediment ecosystems can take years to recover because long‐lived, functionally important species that aid recovery are lost.

Composition Control in CuInZnS2 Nanocrystals by Cation Exchange and Their Phase Transfer

ChemNanoMat, Volume 12, Issue 10, October 2026.
This work elucidates the composition‐defining parameters for CuInZnS2 (CIZS) nanocrystals (NCs) prepared by a cation exchange reaction. Investigations focus on their cation shares and size, which influence both the absorbance and the bandgap. Furthermore, a novel ligand exchange route from 1‐dodecanthiol to 11‐mercaptoundecanoic acid is shown, thereby ...
