The thin-film of hierarchical rutile/anatase TiO₂ nanorod/nanoleafs on fluorine-doped tin oxide glass was prepared via a facile method. For this purpose, the hydrothermal method was used for the synthesis of rutile-phase nanorods on the TiO₂ seeded FTO, and aqueous chemistry was applied for growing anatase-phase nanoleafs on the nanorods. The structural, morphological, and optical properties of coating characterized, and the thin-film utilized as the photoelectrode for dye-sensitized solar cell. The energy conversion efficiency of the newly developed nanostructure was higher than that of TiO₂ nanorod thin-film by 40%. This increase could be ascribed to: (1) superior specific surface area providing dye-holding and light-scattering ability, (2) accelerating charge transport due to direct pathways for photogenerated charge carriers as a result of nanorods presence in the structure, and (3) improving charge separation at the junctions of rutile-phase nanorods and anatase-phase nanoleafs.

通过一种简便的方法制备了氟掺杂氧化锡玻璃上的金红石型/锐钛矿型TiO ₂纳米棒/纳米脂质薄膜。为此，将水热法用于在TiO ₂种子FTO上合成金红石相纳米棒，并将水化学方法用于在纳米棒上生长锐钛矿相纳米叶。表征了涂层的结构，形态和光学性能，并将薄膜用作染料敏化太阳能电池的光电极。新开发的纳米结构的能量转换效率高于TiO ₂纳米棒薄膜减少了40％。这种增加可归因于：（1）提供染料保持和光散射能力的优异比表面积；（2）由于结构中存在纳米棒，光生电荷载流子的直接路径加速了电荷传输；以及（ 3）改善金红石相纳米棒和锐钛矿相纳米叶的结合处的电荷分离。
