Abstract The achievement of both efficiency and stability in perovskite solar cells (PSCs) remains a challenging actively researched topic. In particular, among different environmental factors, ultraviolet (UV) photons play pivotal role contributing to device degradation. this work, by harvesting simultaneously the optical structural properties bottom–up‐synthesized colloidal carbon quantum dots (CQDs), cost‐effective means is provided circumvent UV‐induced degradation PSCs without scarification on their power conversion efficiencies (PCEs). By exploring optimizing number CQDs locations/interfaces where are applied, synergetic configuration achieved photovoltaic performance drop due loss completely compensated increased crystallinity interfacial modification. As result, optimized configurations applied exterior front side as an layer at interface between electron transport absorber, unencapsulated with PCEs >20% fabricated which can maintain up ≈94% initial PCE after 100 h ambient air under continuous UV illumination (5 mW cm −2 ).

Recently emerging perovskite nanocrystals (PNCs) are very attractive fluorescence nanomaterials due to their narrow emission peak, tunable wavelength, and extremely high quantum yield, but chemosensing, biosensing bioimaging applications suffer from the poor stability of ordinary PNCs in aqueous media, especially biological matrices. developed water-stable 2D CsPb2Br5-encapsulated 3D CsPbBr3 (i.e., CsPbBr3/CsPb2Br5 PNCs) show stable light pure water, is seriously quenched media containing molecules chemical reactions. In this work, we used a facile method encapsulate water with SiO2 polyethylene glycol hexadecyl ether (Brij58) into new kind environment-stable (CsPbBr3/CsPb2Br5@SiO2–Brij58). The synthesis target can be accomplished fast, easy, green way. obtained CsPbBr3/CsPb2Br5@SiO2–Brij58 maintain strong for long time, all pH 7.4 PBS, BSA, minimum essential medium, exhibiting excellent environment stability. Moreover, good biocompatibility have been successfully cell imaging. Overall, work provides an low-cost, efficient application bioimaging.

Abstract Formamidinium lead iodide (FAPbI₃) perovskite solar cells (PSCs) hold immense potential for high‐efficiency photovoltaics, but maximizing their open‐circuit voltage ( V OC ) remains challenging. Targeting the inherently stable {111} c ‐dominant facets is a promising approach enhancing stability, formation typically suffers from high defect densities and disordered growth. This study introduces novel using an in situ polymerizable radical molecule, ATEMPO, as additive to address these issues. ATEMPO preferentially interacts with facets, guiding growth forming “radical molecular network‐buffer” upon polymerization. The network effectively mitigates lattice strain, suppresses formation, enhances charge transport via redox‐mediated hopping, provides hydrophobic barrier, significantly improving moisture resistance. strategy yields high‐quality, ‐oriented FAPbI₃ films, leading champion PCE of 25.28% remarkably 1.203 V, corresponding energy loss E only 0.297 eV, among highest reported FAPbI₃‐based PSCs. Furthermore, mini‐module fabricate active area 12.5 cm 2 achieve 21.39%. work paves way developing high‐performance, PSCs minimized photovoltage loss. it offers enhance device longevity environmental concerns.
