Addressing the critical challenges of interfacial defects and insufficient stability in perovskite solar cells, this work introduces a co-solvent engineering strategy to dynamically regulate phenethylammonium chloride (PEACl) passivation layer. The effect isopropyl alcohol (IPA) DMSO: IPA (1:100) mixture as solvent for forming PEACl 2D layer is systematically explored, synergistic interplay between coordination strength crystallization kinetics investigated. blend balances Pb-O (via DMSO) rapid phase separation IPA), enabling oriented growth dense, ultrathin overlayer. This suppresses defect density (electron traps reduced 1.68 × 1015 cm−3) extends carrier lifetime, yielding champion power conversion efficiency (PCE) 24.27%—a significant improvement over control (22.73%). For first time, we establish dual-parameter “solvent coordination-crystallization kinetics” model, providing universal framework designing environmentally benign systems advancing industrial scalability high-performance cells (PSCs).

Abstract We report a highly crystalline self‐assembled multilayer (SAMUL) that is fundamentally different from the conventional monolayer or disordered bilayer used for hole‐extraction in inverted perovskite solar cells (PSCs). The SAMUL can be easily formed on ITO substrate to establish better surface coverage enhance performance and stability of PSCs. A detailed structure‐property‐performance relationship molecules established through systematic study their crystallinity, molecular packing, hole‐transporting properties. These SAMULs are rationally optimized by varying structures deposition methods thermal evaporation spin‐coating fabricating CbzNaphPPA‐based was chosen PSCs due it exhibiting highest crystallinity hole mobility which derived ordered H‐aggregation. This resulted remarkably high fill factor 86.45 %, enables very impressive power conversion efficiency (PCE) 26.07 % achieved along with excellent device (94 its initial PCE retained after continuous operation 1200 h under 1‐sun irradiation at maximum point 65 °C). Additionally, record‐high 23.50 could adopting thermally evaporated SAMUL. greatly simplifies broadens scope SAM large‐area devices diverse substrates.

Abstract The inherent defects (lead iodide inversion and iodine vacancy) in perovskites cause non‐radiative recombination there is also ion migration, decreasing the efficiency stability of perovskite devices. Eliminating these critical for achieving high‐efficiency solar cells. Herein, an organic molecule with multiple active sites (4,7‐bromo‐5,6‐fluoro‐2,1,3‐phenylpropyl thiadiazole, M4) introduced to modify upper interface perovskites. When M4 interacts surface, bromine (Br) site lead (Pb) at surface repair atomic vacancy defects. fluorine (F) Pb correct octahedral crystal lattice distortions eliminate I Additionally, sulfur–iodine (S–I) interactions reduce I–I dimerization It calculated that energy level aligns band gap, promoting charge transfer. As a result, devices achieve 25.1%, stabilized power output (SPO) 25.0%, voltage 1.19 V, fill factor 85.2%. device retains 95% its initial after 2000 h ageing nitrogen atmosphere. Thus, multi‐point cooperative passivation provides effective method improve

Abstract [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic acid (Me‐4PACz) consistently exhibits inhomogeneous distribution on the substrate, which makes it a challenge for growth of high‐quality perovskite film, resulting in undesired interfacial losses at buried interfaces. Moreover, flexible alkyl chains Me‐4PACz are not conducive to intermolecular interactions and hinder charge flow. Here, novel molecule with 4‐Methoxy‐N‐(4‐methoxyphenyl)‐N‐phenylaniline (TPA) carbazole backbone, named CzTPA is designed, constituted Co‐SAM Me‐4PACz.
