Diffraction results. Excerpts from diffraction patterns for MAPbI3 (red), PbI2 (blue), and MAI (cyan) in panel (a). Diffraction patterns for MAPbCl3 (black), PbCl2 (green), and MACl (grey) in panel (b). Diffraction patterns for mixed perovskite (purple), MACl (gray) in panel c). Vertical bars in all panels indicate the position of MAPbI3 (red), MAPbCl3 (black), and PbI2 (blue) peaks according to calculations. All the patterns are reported using a Cu Kα wavelength (1.5418 Å), for direct comparison among data collected at different wavelengths and literature data (complete raw data are reported in Fig. S1).
