Outstanding efficiency (up to 25.2% on glass [1], 19.5% on flexible substrates [2]), low cost, and processability from solution are key advantages of perovskite solar cells (PSC). This technology is rising as a promising candidate for building-integrated photovoltaics, space and automotive applications, and even foldable and lightweight devices for consumer electronics when deployed on flexible substrates [3].Efforts have been made to up-scale the fabrication of PSC to produce large solar modules [4]: well-known techniques such as screen printing, blade-and slot-die coating, inkjet printing have been adapted and tested as possible manufacturing processes. We have focused on an automated spray coating technique [5], starting from the first fundamental layer for the standard nip structure, the electron transport layer (ETL).
