Generate theoretical X-ray diffraction (XRD) patterns to compare against experimental laboratory data.
FAPbI$_3$ exists in different phases:
This is the stable room-temperature phase, but it is not useful for solar cells. 3. Contents of a Sample FAPbI3 CIF File FAPbI3FAPbI sub 3 fapbi3 cif file
CIF file contains the fundamental structural data of Formamidinium Lead Iodide, including: Cell lengths ( ) and angles ( Space Group: The symmetry of the crystal (e.g., for the cubic perovskite phase). Atomic Positions: Fractional coordinates for Lead ( ), Iodine ( ), Carbon ( ), Nitrogen ( ), and Hydrogen (
FAPbI₃ is an organic-inorganic hybrid perovskite. Compared to its predecessor, MAPbI₃ (Methylammonium Lead Iodide), it offers a narrower bandgap (approx. 1.48 eV), which is closer to the ideal Shockley-Queisser limit for single-junction solar cells. This makes it theoretically capable of achieving higher power conversion efficiencies. Contents of a Sample FAPbI3 CIF File FAPbI3FAPbI
A CIF file is the universal text-based standard established by the International Union of Crystallography (IUCr) for sharing structural data. For FAPbI3, the file bridges the gap between raw experimental X-ray diffraction (XRD) data and 3D atomic visualization software.

A typical CIF file contains the following critical data blocks:
-phase (yellow, hexagonal). Understanding this transition starts with the crystal structure. What is a CIF File?
