Resum: Halide perovskite solar cells have revolutionized the photovoltaic field in the last decade. The key point of this success is the low non-radiative recombination that make this family of materials extremely successful not just for photovoltaics but for other optoelectronic and photochemical applications. In this talk I will discuss the work of my group in this field stressing our approach to face the two more important drawbacks for halide perovskite application, the use of hazardous Pb and the longterm stability, that still to be open questions that have not been fully addressed. Sn-based perovskite solar cells exhibit a longterm stability lower than their Pb containing counterparts, making stability their main problem. We will highlight how the use of proper additives can increase significantly the stability of formamidinium tin iodide (FASnI3) solar cells and discuss about the different mechanism affecting this stability.
