It is based on the constructive interference of monochromatic X-rays and a crystalline sample. Unold. Dependence of Phase Transitions on Halide Ratio in Inorganic CsPb(BrxI1-x)3 Perovskite Thin Films Obtained from High-Throughput Experimentation. J. X-Ray diffraction analysis (XRD) is a nondestructive technique that provides detailed information about the crystallographic structure, chemical composition, and physical properties of a material 48. Mainz. Photon flux determination of a liquid-metal jet x-ray source by means of photon scattering. J. X-ray diffractometry (on powder) is a method of qualitative and quantitative physico-chemical analysis. XRDanalysis is a next-generation software package for the analysis of powder diffraction data on Anton Paar’s XRDynamic 500. The figure at the bottom shows the time evolution of a phase transition in a perovskite thin film.įor more information, please see the references: Using weakly focusing optics, the time resolution can reach the sub-second regime – here shown with a measurement of a Cu(In,Ga)Se2 absorber film used for solar cells. This chapter provides a general overview of the process of identifying cell parameters from a powder diffraction pattern. The setup fills a gap between synchrotron beamlines – with high photon flux, but low availability – and standard XRD – with high availability, but insufficient photon flux. aInstitute of Crystallography CNR, Via Amendola 122/o, Bari, I-70126, Italy. At the Helmholtz-Zentrum Berlin (HZB), a MetalJet source is used to investigate chemical and physical reactions during growth or decay of photovoltaic absorber films or in-operando studies of batteries by in-situ 2D-XRD.
