Challenges and Opportunities for Layered Double Perovskite Solar Cells

Solar RRL, Volume 10, Issue 17, 15 September 2026.
Layered lead‐free double perovskites suffer from intrinsic and extrinsic limitations that hinder high photovoltaic performance. This review identifies key challenges, including unfavorable band structures, strong self‐trapping, defect‐induced recombination, processing‐induced inhomogeneity, and device‐level mismatches.

Synthesis and Optical Properties of Diboron Complexes of 1,4‐Anthraquinone Derivatives

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.
