采用水解法制备致密的TiO 2层，以新鲜的亚稳态TiCl 4异丙醇/水溶液为前驱体制备无机-有机混合异质结钙钛矿太阳能电池。以2 mol/L的TiCl 4与异丙醇按1：3的体积比稀释的水溶液为前驱液，制备的TiO 2膜层均匀致密，膜厚为126 nm。相应的钙钛矿太阳能电池给出了10.61%的光伏转换效率。
A hydrolysis process was applied to prepare the compact TiO2 layer using the fresh metastable TiCl4 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%.
