Halide perovskite solar cells have revolutionized the photovoltaic field in the last decade. In a decade of intensive research it has been a huge improvement in the performance of these devices, however, the two main drawbacks of this system, the use of hazardous Pb and the long term stability, still to be open questions that have not been fully addressed. Sn-based perovskite solar cells are the devices presenting the highest performance after Pb-based but significantly below them. In addition, Sn-based perovskite solar cells exhibit a long term stability lower than their Pb containing counterparts, making stability their main problem. In this talk, we highlight the use of additives to increase significantly the stability of formamidinium tin iodide (FASnI3) solar cells, and discuss about the different mechanism affecting this stability, beyond the oxidation of Sn2+. Another important challenge for the commercialization of this technology is the up-scaling of the Sn-perovskite deposition especially due to the fast crystallization producing inhomogeneous thin films. Here, we will analyze the up-scaling of these devices by the use of blade coating and analyze the important effect of additives in the control of Sn-perovskite film crystallization.
