Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

open access: yesAdvanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

open access: yesAdvanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Texture‐Enhanced Mechanical Stability of Transparent Electrodes for Flexible Optoelectronics with Near‐Infrared Response

open access: yesAdvanced Materials Interfaces, EarlyView.
Texturing of indium tin oxide (ITO) electrodes on plastic substrates is found to enable both, a remarkable transparency up to the near‐infrared region, and a massively enhanced mechanical stability upon bending. Therefore, textured ITO electrodes are an appealing option for flexible opto‐electronic applications with near‐infrared response, such as all ...

Beta‐Lactoglobulin for Water‐Based and Tunable Nanostructure Templating of Printed Titania Thin Films: The Influence of pH Value and Protein Concentration

open access: yesAdvanced Materials Interfaces, EarlyView.
The synthesis route for the fabrication of nanostructured titania thin films focuses on water‐based solutions, abundant, nontoxic materials, and a highly scalable deposition technique. Using beta‐lactoglobulin enables tunable titania thin film templating and allows for different domain sizes, porosities, and morphologies.
