High-performance and cost-effective hole-collecting materials (HCMs) are indispensable for commercially viable perovskite solar cells (PSCs). Here, we report an anchorable HCM composed of a triazatruxene core connected with three alkyl carboxylic acid groups (3CATAT-C3). In contrast to the phosphonic acid-containing tripodal analog (3PATAT-C3), 3CATAT-C3 molecules can form hydrophilic monolayer on transparent conducting oxide surface, which is beneficial subsequent film deposition in traditional layer-by-layer fabrication process. More importantly, larger diffusion coefficient higher surface energy make suitable simplified, one-step co-deposition process was directly added as part precursor solution. predominantly located at bottom after spin-coating mixed solution, facilitating charge extraction. Devices fabricated by this method exhibit superior performance champion power conversion efficiency over 23%. The unencapsulated devices showed good operational stability (retaining 90% initial output 100 h), thermal durability 95% value heating 105 °C under air), excellent storage (showing no drop 8000 h). Based results time-of-flight secondary-ion mass spectroscopy (ToF-SIMS) order nuclear magnetic resonance (DOSY), elucidated effect anchoring HCMs PSCs well mechanism Our findings provide valuable insights molecular design multifunctional materials, further advancing cells.

Abstract Rational regulation of Me‐4PACz/perovskite interface has emerged as a significant challenge in the pursuit highly efficient and stable perovskite solar cells (PSCs). Herein, an organometallic molecule aluminum glycinate (AG) that contained amine (‐NH 2 ) hydroxyl (Al‐OH) groups is developed to tailor buried minimize interface‐driven energy losses. The Al‐OH selectively bonded with unanchored O═P‐OH bare NiO‐OH optimize surface morphology levels, while ‐NH group interacted specifically Pb 2+ retard crystallization, passivate Pb‐related defects, release residual stress. These interactions facilitate carrier extraction reduce losses, thereby realizing balanced charge transport. Consequently, AG‐modified narrow bandgap (1.55 eV) PSC demonstrates efficiency 26.74% (certified 26.21%) fill factor 86.65%; wide (1.785 realizes 20.71% champion excellent repeatability. PSCs maintain 91.37%, 91.92%, 92.00% their initial after aging air atmosphere, nitrogen‐filled atmosphere at 85 °C, continuously tracking maximum power‐point under one‐sun illumination (100 mW cm −2 for 1200 h, respectively.

The development of hole-collecting materials is indispensable to improving the performance perovskite solar cells (PSCs). To date, several anchorable molecules have been reported as effective monolayer (HCM) for p–i–n PSCs. However, their structures are limited well-known electron-donating skeletons, such carbazole, triarylamine, etc. In this work, we developed a series squaraine derivatives that π-conjugated core composed squaric acid moiety connected an indoline moiety. Thanks polar carbonyl group acid, all were found form hydrophilic monolayers after being chemisorbed on transparent conducting oxide surfaces, which beneficial subsequent deposition layer. effect substituents and anchoring groups molecular electronic structure well cell device's was elucidated. PSC devices fabricated by using these exhibited high power conversion efficiencies up 22.1%, together with good stability. This work highlights potential simple skeleton building block realize high-efficiency cost-effective

Hole-selective layers (HSLs) are critical for efficient and stable perovskite solar cells (PSCs). Chlorophylls (Chls) their analogs exhibit unique optoelectronic properties, making them attractive photovoltaics. However, dopant-free Chl-based materials remain underexplored, with reported power conversion efficiencies (PCEs) below 19%. This study investigates three nickel chlorins (NiChls) as monomers functional materials. Nickel methyl pyropheophorbide-a (NiChl-Oxo), derived from natural Chl-a, was chemically modified at the C13-keto-carbonyl group, yielding NiChl-Deoxo NiChl-CN. Electrochemical polymerization used to fabricate corresponding polymerized NiChl films HSLs. Without dopants, NiChl-Deoxo-based PSCs achieved a record PCE of 21.8%, fill factor 83.8%, which is highest efficiency date. Additionally, these devices exhibited exceptional long-term stability. highlights effectiveness strategic molecular modifications in advancing presents promising pathway developing high-performance, HSLs next-generation PSCs.
