摘　　要：为系统研究锐钛矿相的TiO_(2)纳米棒阵列的转化时间对其微结构与相应Sb_(2)S_(3)太阳电池光伏性能的影响,通过使用水热法在FTO导电玻璃/TiO_(2)致密层衬底上沉积了长度、直径、面密度分别为510nm、45nm、250μm^(-1)的ZnO纳米棒阵列,以FTO导电玻璃/TiO_(2)致密层/ZnO纳米棒阵列为模板,利用(NH_(4))_(2)TiF_(6)和H_(3)BO_(3),将ZnO纳米棒阵列成功地转化为锐钛矿相TiO_(2)纳米棒阵列。使用SbCl_(3)与Tu配合物的DMF溶液作为前驱体溶液,通过旋涂热解法在所得锐钛矿相TiO_(2)纳米棒阵列上沉积了Sb_(2)S_(3)薄膜,以spiro-OMeTAD作为空穴传输层,组装了Sb_(2)S_(3)敏化TiO_(2)纳米棒阵列太阳电池。以FTO导电玻璃/TiO_(2)致密层/锐钛矿相TiO_(2)纳米棒阵列为衬底组装的全固态Sb_(2)S_(3)太阳电池获得了4.96%的光电转换效率。To study the effect of conversion time of anatase TiO_(2) nanorod arrays on their microstructure and photovoltaic performance of corresponding Sb_(2)S_(3) solar cells,the ZnO nanorod arrays were deposited on the FTO/TiO_(2) compact layer with the length of 510nm,diameter of 45nm,and surface density of 250μm^(-1) by using hydrothermal.By taking the FTO/TiO_(2) compact layer/ZnO nanorod arrays as a template,the ZnO nanorod arrays were successfully transformed into anatase TiO_(2) nanorod arrays by using ammonium hexafluorotitanate((NH_4)_(2)TiF_(6)) and boric acid(H_(3)BO_(3)).The Sb_(2)S_(3) thin films were deposited on the anatase TiO_(2) nanorod arrays with the pyrolysis method by using SbCl_(3) and Tu complex solution in DMF.The corresponding solar cells were also fabricated with spiro-OMeTAD as the hole transport layer.And the Sb_(2)S_(3) solar cells assembled with the FTO/TiO_(2) compact layer/anatase TiO_(2) nanorod arrays achieved the photoelectric conversion efficiency of 4.96%.
