Controlling the microstructure of halogenated hybrid perovskite thin films used in solar cells is essential to optimize their performance. we were interested in the deformation state of perovskite films by X-ray diffraction and study the orientation of the crystal lattice in these films by X-ray diffraction microscopy. The stability of the different domain orientations is studied by DFT and illustrates the determining role of the chemical environment at the film-substrate interface.
