Hydrolysis preparation of the compact TiO₂ layer using metastable TiCl₄ isopropanol/water solution for inorganic–organic hybrid heterojunction perovskite solar cells

【摘要】 A hydrolysis process was applied to prepare the compact Ti O2 layer using the fresh metastable Ti Cl4isopropanol/water solution as the precursor solution for the preparation of the inorganic–organic hybrid heterojunction perovskite solar cells. The optimal compact Ti O2 layer prepared from the aqueous solution of 2 mol/L Ti Cl4 diluted in isopropanol at 1 : 3 by volume as precursor solution was uniform and with a film thickness of 126 nm.The corresponding perovskite solar cell gave a photovoltaic conversion efficiency of 10.61%.更多还原
