At temperatures exceeding $\approx$ 330 K, FAPbI$_3$ stabilizes in a cubic structure.
FAPbI₃ (formamidinium lead iodide) is a hybrid organic-inorganic perovskite with the chemical formula HC(NH₂)₂PbI₃. It is a promising light-absorbing material in high-efficiency perovskite solar cells (PSCs) due to its optimal band gap (~1.48 eV) and excellent thermal stability compared to its methylammonium counterpart (MAPbI₃). fapbi3 cif file

By comparing experimental X-ray Diffraction (XRD) patterns with the theoretical pattern generated from a CIF file, scientists can confirm if they have successfully synthesized the desired phase. and their applications.
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.
