One Stone Two Birds: Sustainable Perovskite Solar Cells Obtained by Using Water‐Based Recycled PbI2 and Guanidinium Thiocyanate Post‐Treatment

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
A simple water‐based recycling and recrystallization method enables the recovery of high‐purity PbI2 from spent perovskite solar cells. With guanidinium thiocyanate treatment to restore film quality, PSCs fabricated using the recycled PbI2 achieve a PCE of 17.25%, comparable to those made from commercial high‐purity PbI2. This scalable, cost‐effective,

Characterizing electronic noise interference from the external laser positioning system on a radiation therapy MRI simulation scanner

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Magnetic resonance imaging (MRI) for radiation therapy treatment planning is currently being used in many anatomical sites to better visualize soft tissue landmarks, a technique known as an MRI simulation. A core component of modern MRI simulation configurations are the use of external laser positioning systems (ELPS) to help set up

Lattice‐Matched 2D Template Enables Efficient Cesium Tin Halide Perovskite Solar Cells

Advanced Materials, Volume 38, Issue 45, 13 August 2026.
Lattice‐matched 2D perovskite PEA2CsSn2I7 templates the out‐of‐plane growth of inorganic 3D γ‐CsSnI3 along the (110) plane, forming highly oriented 2D/3D tin halide perovskite heterostructures. With reduced trap states and mitigated δ‐phase impurities, the CsSnI3‐based solar cells achieve a power conversion efficiency of 15.27% and maintain stable ...

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

Advanced Materials, Volume 38, Issue 44, 7 August 2026.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

High Efficiency 3‐Tandem Top Emitting Pure‐Blue OLEDs Beyond the BT.2020 Blue Standard

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
We report a high‐efficiency ultrapure‐blue 3‐tandem TEOLED through synergistic optimization of a narrowband MR‐TADF emitter, Purcell‐based cavity design, and pure Ag cathode/CPL structure. The optimized device achieves 463 nm emission, an ultranarrow FWHM of 10 nm, CIE y of 0.040, and a blue index of 1,596 cd/A/y, surpassing the BT.2020 blue standard ...
