Films fabricated via laboratory-sale spin-coating and industrially compatible spray-coating process, respectively, are compared with each other to optimize both the film-coating quality and corresponding device performance. This is validated by the photovoltaic performance of prototype devices with three spray-coated layers with the active area of 1 × 1 cm2. The champion cells achieve a power conversion efficiency of 10.09%, which is one of the highest efficiencies obtained from fully spray-processed large-area perovskite solar cells thus far. Furthermore, these results reinforce the feasibility of the spray-coating methodology for the fabrication of multilayers within perovskite solar cells stack and low-cost route toward upscaling the manufacturing alternatives to spin coating. ? 2020 WILEY-VCH Verlag GmbH & Co.
