Structural parameters of the MAPbI3 crystal phase of Pero1 (black line, circle symbols) and Pero2 (red line, square symbols) samples determined by fitting the PDF profiles, plotted as a function of the temperature of the sample during the in situ experiment. Weight fraction (a), dihedral angle I2—Pb—Pb—I2 (b), methyl­ammonium shape parameter (c), displacement parameter for I2 atoms (d), and cell parameters a (e) and c (f).
