Organometal halide perovskites, have been shown to be great candidates for photovoltaics, owing to the strong solar absorption and the high mobility and low recombination rates of photo-generated charge carriers in these compounds. Subsequently, solar cells made from perovskites have reached efficiencies of more than 20%, making them comparable with commercially available silicon solar cells. The performance of the perovskite cells greatly depend on their crystal morphology. We fabricate and characterise different cells by varying processing parameters including film deposition methods, annealing temperature and solvent media. By means of X-ray scattering methods, we gain insight into the inner film morphology and thus are able to correlate morphology and photovoltaic performance, with the target to get better fundamental understanding.
