Controlling the microstructure of halogenated hybrid perovskite thin films used in solar cells is essential to optimize their performance. Researchers at IRIG are 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.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
