The desire to efficiently convert solar into electric energy has lead to increasing activity in the associated field of scientific research in the last decades. Due to major advantages, as low material costs and the applicability of mass production techniques, solution processsed solar cells have long been of particular interest; disadvantages such as comparatively low efficiency and fast degradation inhibited mass production so far. Combining advantages of organic and inorganic systems, perovskite solar cells - as hybrid organic-inorganic cells - have shown a skyrocketing rise in efficiency for the last years to currently around 20 %. However, little is known about the formation of the perovskite film under different conditions on a crystal size level, which is of key importance for the understanding of how to further improve this type of solar cells. Therefore the aim of this project is to use multiple measurement techniques, in particular Grazing Incidence Wide Angle X-ray Scattering (GIWAXS), on perovskite films with standard and systematically altered production procedures to learn about the film formation and possibilities of specific manipulation.
