Abstract The efficiency of solar cells based on organic–inorganic hybrid perovskite materials has already met the standards for commercial applications. However, there remains an gap ≈30% between small‐area devices and industrial‐scale devices. Large‐area devices, in particular, tend to exhibit lower optoelectronics reduced environmental stability. ink fluid behavior significantly influences crystal process large‐area films during printing fabrication, which cannot be disregarded. As manufacturing area total solvent volatilization increase, impact inhomogeneous migration by colloidal particles gradually intensifies. This work focuses elucidating rheological properties crystalline quality device optoelectronic performance deposition. It explores throughout process, effects additives motion particles, how ink's change when modifying agents interact with particles. Additionally, functional aspects controlling film formation optimizing photovoltaic (PSCs) are thoroughly discussed.

The primary challenge in commercializing perovskite solar cells (PSCs) mainly stems from fragile and moisture-sensitive nature of halide materials. In this study, we propose an asynchronous cross-linking strategy. A multifunctional initiator, divinyl sulfone (DVS), is firstly pre-embedded into precursor solutions. DVS, also as a special co-solvent, facilitates intermediate-dominated crystallization manipulation, favouring formamidine-DVS based solvate transition. Subsequently, DVS-embedded as-cast films are post-treated with nucleophilic reagent, glycerinum, to trigger controllably three-dimensional co-polymerization. resulting scaffold provides enhanced water-resistance, releases residual tensile strain, suppresses deep-level defects. We achieve maximum efficiency over 25% (certified 24.6%) VOC 1.229 V, corresponding mere 0.30 V deficit, reaching 97.5% the theoretical limit, which highest reported all systems. This strategy generally applicable efficiencies approaching 26%. All-around protection significantly improves PSC's operational longevity thermal endurance. Here, authors multi-functional high-performance stable devices voltage deficit.

Flexible perovskite solar cells (f-PSCs) are considered the most promising candidates in portable power applications. However, high sensitivity of crystallization on substrate and intrinsic brittleness usually trade off performance f-PSCs. Herein, we introduced an initiator-free cross-linkable monomer (2,5-dioxopyrrolidin-1-yl) 5-(dithiolan-3-yl)pentanoate (FTA), which can chemically passivate defects enable real-time fine regulation crystallization. The resulting film exhibited higher crystallinity, enlarged grain size, reduced dependence substrate. In addition, cross-linked FTA [CL(FTA)] distributed along boundaries effectively released residual stress securely bound grains together. Consequently, CL(FTA)-modified flexible PSCs achieved a record-breaking efficiency 24.64% (certified 24.08%). Moreover, scalable potential has been verified by corresponding rigid modules, delivering impressive efficiencies 19.53 17.13%, respectively. Furthermore, optimized device demonstrated bending durability improved operational stability, thereby advancing progress f-PSCs toward industrialization.
