The formation of perovskite thin films is of interest since this process determines the final material quality. In-situ X-ray scattering can help to learn more about the formation of perovskite crystals and how the crystallization is altered by the use of additives or other parameters. The film formation mechanism directly influences the performance of, for example, solar cells. We apply different techniques to extract time-resolved information and will show the opportunities and limitations of these in the quest for understanding formation-function relationships in perovskites.
