In the last decade, perovskite solar cells (PSCs) have shown great potentialities in developing low cost, flexible, lightweight and high-throughput new generation photovoltaic technology. Many factors can affect the PSCs efficiency and stability and nowadays several strategies have been proposed to improve the perovskite layer morphology and to optimize the perovskite/charge transporting layer interfaces. Indeed, among the several formulation proposed for perovskite precursor solution till now, double cation perovskite, using Cs+ and FA+ as cations and PbI2/PbBr2 as halogen precursors demonstrated superior photochemical stability, providing a viable route for the device scaling-up from lab-scale device to large area module[1]. In this work the Perovskite deposition has been carried out by a double step technique outside the glove box, with relative humidity below 30%, using an automatized blade/slot die coater designed and made by Cicci Research srl. The results are promising as the technique used does not involve the use of Solvent Engineering, making the process scalable in the air.
