Solution processable hybrid halide perovskites solar cells have been extensively studied over the last ten years and great advances in efficiency have been achieved. An important factor for the performance of the final solar cell is the morphology of the perovskite layer. Therefore, control of structure formation mechanisms is highly desirable. [1] We investigate systematically the processing of the active layer to determine processing parameters that are decisive for structure formation. To reliably study the effect of time relevant processing steps on the perovskite layer, we use automated processing. Applying photoluminescence, optical microscopy and grazing incidence wide angle X-ray scattering (GIWAXS) allows us to determine the morphology on the nano and micron scale and detect the correlations between processing and efficiency.
