Tin halide perovskites are highly interesting alternatives to lead-based materials for a range of optoelectronic applications. However, their defect content and characteristics, heavily determined by the crystallization process of these materials, has slowed down their development. In this talk, we will cover the main differences in solution properties between lead and tin defining the current limitations of the latter. We will also discuss the actual potential of traditional and novel strategies to deal with this challenge, particularly regarding the solvent nature. Finally, a wide range of solution and thin-film characterization will give us a comprehensive understanding of the key parameters and how to use them to effectively control tin-based perovskite crystallization. This talk aims to provide both an overview and a set of directions to overcome current limitations in tin halide perovskite applications through completely new processing systems. Furthermore, beyond tin-containing perovskites, the fundamental character of this work maked it of high interest also for other similar novel materials under development.
