Vertically aligned rutile TiO2 nanowire arrays (NWAs) with lengths of ∼44 μm have been successfully synthesized on transparent, conductive fluorine-doped tin oxide (FTO) glass by a facile one-step solvothermal method. The length and wire-to-wire distance of NWAs can be controlled by adjusting the ethanol content in the reaction solution. By employing optimized rutile TiO2 NWAs for dye-sensitized solar cells (DSCs), a remarkable power conversion efficiency (PCE) of 8.9% is achieved. Moreover, in combination with a light-scattering layer, the performance of a rutile TiO2 NWAs based DSC can be further enhanced, reaching an impressive PCE of 9.6%, which is the highest efficiency for rutile TiO2 NWA based DSCs so far.
通过简便的一步溶剂热法，成功地在透明导电掺氟氧化锡（FTO）玻璃上合成了长度约为 44μm 的垂直排列的锐钛矿 TiO2 纳米线阵列（NWAs）。通过调整反应溶液中的乙醇含量，可以控制 NWAs 的长度和线对线距离。通过采用优化的锐钛矿 TiO2 NWAs 用于染料敏化太阳能电池（DSCs），实现了显著的功率转换效率（PCE）为 8.9%。此外，通过与光散射层结合，锐钛矿 TiO2 NWAs 基 DSC 的性能可以进一步提高，达到令人印象深刻的 PCE 为 9.6%，这是迄今为止基于锐钛矿 TiO2 NWA 的 DSCs 的最高效率。
