Laboratory-scale spin-coating techniques are widely employed for fabricating small-size, high-efficiency perovskite solar cells. However, achieving large-area, high-uniformity films and thus cell devices remain challenging due to the complex fluid dynamics drying behaviors of precursor solutions during large-area fabrication processes. In this work, a high-quality, pinhole-free, FAPbI3 film is successfully obtained via scalable blade-coating technology, assisted by novel bidirectional Marangoni convection strategy. By incorporating methanol (MeOH) as balance agent, direction effectively regulated, mitigating disordered motion colloidal particles printing process. As result, champion power conversion efficiencies (PCEs) 24.45% 20.32% achieved small-area (0.07 cm2) modules (21 cm2), respectively. Notably, under steady illumination, device reached stabilized PCE 24.28%. Furthermore, unencapsulated exhibited remarkable operational stability, retaining 92.03% its initial after 1800 h ambient conditions (35 ± 5% relative humidity, 30 °C). To demonstrate universality strategy, blue light-emitting diode fabricated, showing an external quantum efficiency (EQE) 14.78% electroluminescence wavelength (EL) 494 nm. This work provides significant technique advancing solution-processed, industrial-scale production high-quality stable
