Summary / Abstract: In the last decade, perovskite solar cell (PSC) technology showed an efficiency improvement from 9.7% to 25.2% approaching the Si record of more than 26%. The low-cost perspective of PSCs is achievable only if scalable processes in manufacturing conditions such as pilot line or plant factory are designed and optimized for the full device stack. Here, we demonstrate a semi-automatic and scalable solvent quenching/doublestep method, based on the blade-coating technique, to deposit the triple cation perovskite in ambient air on module size. We assess the homogeneity of the perovskite layer and of the full stack by scanning electron microscopy images and profilometry measurements. Moreover, we compared the efficiency of modules fabricated by different deposition procedures: blade-coating in ambient air, spin-coating in nitrogen air and ambient air. In the first case the efficiency was about 16%, while the spin-coating technique exhibited efficiencies about 15% and 13% in nitrogen and ambient air, respectively.
