Hierarchical anatase TiO(2) nano-architecture arrays consisting of long TiO(2) nanowire trunk and numerous short TiO(2) nanorod branches on transparent conductive fluorine-doped tin oxide glass are successfully synthesized for the first time through a facile one-step hydrothermal route without any surfactant and template. Dye-sensitized solar cells based on the hierarchical anatase TiO(2) nano-architecture array photoelectrode of 18 μm in length shows a power conversion efficiency of 7.34% because of its higher specific surface area for adsorbing more dye molecules and superior light scattering capacity for boosting the light-harvesting efficiency. The present photovoltaic performance is the highest value for the reported TiO(2) nanowires array photoelectrode.
首次通过简便的一步水热法在透明导电掺氟氧化锡（FTO）玻璃上成功合成了由长 TiO2 纳米线主干和大量短 TiO2 纳米棒分支组成的分级锐钛矿 TiO2 纳米结构阵列。由于其具有更高的比表面积，可吸附更多的染料分子，以及更好的光散射能力，可提高光捕获效率，基于长度为 18μm 的分级锐钛矿 TiO2 纳米结构阵列光电管的染料敏化太阳能电池的功率转换效率达到了 7.34%。目前的光伏性能是报道的 TiO2 纳米线阵列光电管的最高值。
