水解工艺制备致密的TiO2层使用新鲜的亚稳的TiCl4异丙醇水溶液为有机-无机杂化钙钛矿结构的异质结太阳能电池的制备前驱体溶液。从2 mol/L TiCl4稀释在1的异丙醇水溶液制备的最佳紧凑型TiO2层:3体积为前驱体溶液均匀,膜的厚度为126纳米。相应的钙钛矿型太阳能电池的光电转换效率为10.61%。
A hydrolysis process was applied to prepare the compact TiO2 layer using the fresh metastable TIC14 isopropanol/water solution as the precursor solution for the preparation of the inorganic-organic hybrid heterojunction perovskite solar cells. The optimal compact TiO2 layer prepared from the aqueous solution of 2 mol/L TiCl4 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%.
