Title Fabrication and characterization of perovskite solar cells
with new structure
Abstract By comparing different structures of perovskite solar cells, planar structure was chosen for this diploma work due to its merits of high efficiency, simple structure, and convenient fabrication.The author explored the fabrication progress of planar perovskite solar cells, including synthesis of the precursors for different functional layers, different solution-based coating technologies, and characterization of surface topography. Fabrication of titanium dioxide thin film was studied as emphasis. Titanium dioxide sol precursor was prepared, and spin-coating as well as electrospraying methods were used for thin film fabrication. The coating parameters were optimized, and high-quality titania thin film was obtained. Different methods of perovskite film fabrication was explored, including one-step, two-step and adjusting the composition ratio. The fabricated perovskite solar cells were tested and I-V curve obtained for further data analysis.
