| 摘要: 运用连续吸附反应法和化学腐蚀-沉积法，用ZnO/FTO（氟掺杂氧化锡）多孔纳米片为模板，制备了TiO2/FTO多孔纳米片。研究了吸附次数对形貌、光散射性能和染料敏化太阳电池性能的影响。最佳吸附次数为30，由此得到的太阳能电池的效率、短路电流密度Jsc、开路电压Voc和填充因子FF分别为：5.57%、9.26 mA·cm-2、0.835 V和72.04%。这个效率略高于P25（5.32%），但远高于ZnO（2.41%）。 | |

| Abstract: A strategy was presented for synthesizing TiO2 nanosheets on fluorine-doped tin oxide (FTO) glass substrate through layer-by-layer absorption and reaction (LBL-AR) method using porous ZnO nanosheets as a template, followed by wet-chemical etching and depositing process. The effect of immersing cycles on the morphology, optical property and performance of dye-sensitized solar cells (DSSCs) has been demonstrated. A maximum efficiency of 5.57% is obtained from 30 cycles of immersing, with a short-circuit current density (Jsc) of 9.26 mA·cm-2, open-circuit voltage (Voc) of 0.835 V and fill factor (FF) of 72.04%. The maximum efficiency achieved is a little higher than that of cell-P25 (5.32%) and much higher than that of ZnO nanosheets (2.41%). | |
