Abstract
In order to meet the demands of tandem solar cells in the future, this research aims to produce semi-transparent perovskite solar cells. After the control of the materials and the optimization of the perovskite solar cell manufacturing process, the scale-up development is carried out. Developed a high quality TiO2 structure with blocking/porous double layers by sputtering and screen printing, which greatly reduces the leakage current. By adding a trace amount of anti-solvent to the perovskite precursor solution, the crystallinity of the perovskite absorption layer is improved. The development of doctor blade coating hole transmission layer and sputtering transparent conductive layer to verify the efficiency of semi-transparent perovskite solar cells.
