Efficient and Durable Semitransparent Perovskite Solar Cells for the Application in 4T Perovskite/c‐Si Tandem Devices

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 887-905, July 2026.
We present an optimized fabrication strategy incorporating a solution‐processed SnO2 buffer layer that prevents sputter‐induced damage during TCO deposition, enabling semitransparent perovskite solar cells with 21.87% efficiency, 27.15% in tandem, and exceptional long‐term stability under continuous illumination and outdoor conditions.

Site‐Selective Functionalization of Cysteine Units in Peptides Through Meerwein Arylation Reactions Under Mild Conditions

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
α‐Methylstyrenes are known as highly efficient scavengers for aryl radicals. Herein, a bifunctional reagent is introduced that merges a 2‐bromoacyl moiety for thiol coupling with a styrene unit for subsequent radical functionalization. The sequential transformations proceed under mild conditions, enabling selective cysteine modification in peptidic ...

Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Mechanochemical SNAr on Phthalonitriles: Distinct Reactivity and Selectivity in One‐Pot Synthesis for Greener Phthalocyanines

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
Mechanochemical nucleophilic aromatic substitution enables efficient, reproducible functionalization of phthalonitriles under minimal solvent conditions with high versatility. Integrating this process with solid‐state cyclotetramerization affords metalated and metal‐free phthalocyanines in a streamlined sustainable one‐pot workflow.

In Vitro Biological Activities of Piper corcovadensis C.DC.: Antioxidant, Antineoplastic‐Related and Antibacterial Effects

The FASEB Journal, Volume 40, Issue 11, 15 June 2026.
Piper corcovadensis extract is rich in bioactive compounds with antioxidant potential, capable of decreasing ROS levels; antitumor activity in cutaneous melanoma cells SK‐MEL‐28; and anti‐inflammatory activity, decreasing the expression of IL‐6 and NLPR3 genes and increasing TNF expression, without cytotoxicity to healthy peripheral blood cells (PBMCs).

ZnMgO/Se Thin Film Photovoltaic Devices With Graphene/Silver Nanowire Stacked Flexible Transparent Conducting Electrodes

physica status solidi (a), Volume 223, Issue 11, 10 June 2026.
The graphene/AgNW transparent conductive electrode (TCE) was applied to ZnMgO/Se photovoltaic devices. Device with sol–gel ZnO layers that protected from sputtering damage clearly exhibited photovoltaic effect. As compared with devices using conventional indium tin oxide (ITO) TCEs, photovoltaic devices containing graphene/AgNW TCEs showed a 56 ...
