Starting from solutions, the formation of the perovskite structure for hybrid organic-inorganic components used for solar cells depends strongly on a multitude of parameters during processing. Similar to other known structure formation processes, also the perovskite formation can be divided into different stages. Additives can for example be used to suppress structure formation in a certain stage [1]. Equally the timing available of the various stages is relevant for the final structure as can be systematically shown by changing the processing atmosphere [ACS Appl. Mater. Interfaces, accepted] or processing method [2] and even individual processing parameters. Exploring the relevance of the individual steps in structure formation will help us understand how to achieve reproducible nanostructures and hence reliable material properties.
