Abstract The interface stability and non‐radiative recombination loss of the cathode greatly limit performance inverted perovskite solar cells (PSCs). Here, an efficient multifunctional anti‐corrosive modification strategy based on 2,2′‐(1,3‐phenylene)‐bis[5‐(4‐tert‐butylphenyl)‐1,3,4‐oxadiazole] (OXD‐7) is proposed to overcome issues. OXD‐7 molecules chemically coordinate Ag electrode form a stable complex film OXD7‐Ag, which suppresses halide ion migration thus enhances corrosion...
Abstract The solubility problem of conjugated polymers in nonhalogenated solvents limits the application Organic solar cells (OSCs). By combining with a hot spin‐coating process, efficient PM6:BTP‐BO‐4F:GS‐ISO ternary OSCs are prepared by employing o‐xylene as solvent. After adding 10 wt% content GS‐ISO to PM6:BTP‐BO‐4F, surface morphology active layers is improved and charge extraction, transport, collection enhanced. Compared efficiency PM6:BTP‐BO‐4F (16.25%), an 18.63% achieved for OSCs....
Direct functionalization of a C-H bond at either the meta or para position by only changing catalyst system poses significant challenge. We herein report [Fe(TPP)Cl]-enabled, selective, difluoromethylation arenes using BrCF2CO2Et as source, which successfully altered selectivity from to position. A preliminary mechanistic study revealed iron porphyrin complex not activated aromatic ring but also induced due influence ligand sterics.
Carbon-based mesoscopic perovskite solar cells (MPSCs) are becoming one of the most competitive photovoltaic technologies owing to their lower manufacturing cost and excellent stability. In this work, methylammonium acetate (MAAc), an ionic liquid additive, is added into lead triiodide (MAPbI3) used fabricate high-performance MPSCs. Systematic detailed studies have shown that MAAc interacts with PbI2 preferentially form a MAPbI3-x(Ac)x intermediate phase can effectively control...
Abstract Efficient modification of the interface between metal cathode and electron transport layer are critical for achieving high performance stability inverted perovskite solar cells (PSCs). Herein, a new alcohol‐soluble rhodamine‐functionalized dodecahydro‐ closo ‐dodecaborate derivate, RBH, is developed applied as an efficient interlayer to overcome (6,6)‐phenyl‐C 61 butyrie acid methyl ester (PCBM)/Ag issues. By introducing RBH interlayer, functions traps passivation, interfacial...
Additive strategies play a critical role in improving the performance of organic solar cells (OSCs). There are only few reports on application solid additives for OSCs, which leaves large space further improvement and study relationship between material structure property.

In this study, using PM6:L8-BO as the main system and non-fullerene acceptor IDIC third component, a series of ternary organic solar cells (TOSCs) are fabricated. The results reveal that plays significant role in enhancing performance TOSCs by optimizing morphology blended films forming interpenetrating nanostructure. improved film facilitates exciton dissociation collection TOSCs, which causes an increase short-circuit current density (JSC ) fill factor (FF). Further, content, power...
