      abstract     = {Tin-based perovskites have shown significant potential for
                      photovoltaics applications due to their reduced toxicity and
                      ideal bandgap when compared with the Pb counterpart.
                      However, the utilization of industry-compatible and scalable
                      fabrication techniques has remained limited to date, due to
                      the unique crystallization properties of tin-based
                      perovskites. Here, tin perovskite solar cells prepared using
                      a two-step blade coating process is reported. The broad
                      exploration of the space of parameters and the corresponding
                      crystallization control mechanisms showed that waiting time
                      and solvent nature are equally important as coating speed
                      and coating temperature in enhancing the quality of tin(II)
                      iodide films deposited in the first step and the subsequent
                      conversion in the second step. Highly reproducible and
                      efficient tin-based devices are achieved, exhibiting a
                      maximum power conversion efficiency (PCE) of $10.7\%$ and an
                      impressive fill factor (FF) of $79\%.$ To the knowledge,
                      these values are among the highest reported thus far using a
                      scalable technique. Additionally, it is important to notice
                      that the devices retain over $90\%$ of the initial PCE over
                      4 months in an inert atmosphere and exhibit good operational
                      stability. The results demonstrate a clear roadmap towards
                      fabricating tin perovskite devices with industry-compatible
                      techniques.},
