Understanding FAPbI₃: The Power of the CIF File in Perovskite Research

If your sample is yellow rather than black, you are likely looking for the Delta ( ) phase (Hexagonal, P63mccap P 6 sub 3 m c ), which is photo-inactive.

In the realm of chemistry and materials science, the Crystallographic Information File (CIF) format has emerged as a standard for representing and exchanging crystallographic data. Among the various CIF files used in these fields, the FAPBI3 CIF file holds significant importance. This article aims to provide a detailed understanding of FAPBI3 CIF files, their structure, and their applications.
