Diffraction Full Field Imaging on Perovskite Samples

Abstract

In this thesis a method to image organic inorganic hybrid perovskites using full field X-ray diffraction microscopy is introduced. Diffraction microscopy is used to image hybrid perovskites. It was found that lead halide perovskite solar cells show interesting structural behaviour under an applied voltage, which is evidence that structural relaxation might be the cause of the anomolous hysteresis observed in these structures.
