Photovoltaic solar cells have been regarded as a promising energy conversion method to keep up with the worlds increasing energy consumption. Organic solar cells yield promising prospects due to their low cost fabrication, light weight and mechanical flexibility. However, the efficiency of organic solar cells are inferior to commercial silicon solar cells. Organometal halide perovskite solar cells are a product of combining the advantages of organic and inorganic systems. The steep rise of the efficiency makes them the fastest-advancing solar cell technology to date. Properties of the perovskite material like large carrier diffusion lengths, high charge-carrier mobilities and low exciton binding energy all contribute to superior performance.
In this work, we fabricated mesoscopic perovskite solar cells by using a screenprinter. We analyze processing parameters and investigate the influence on the efficiency of the solar cell. To obtain fully printed solar cells, slot die coating is compared to drop casting of the perovskite materials onto the printed layers.
