摘要：

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 (J(sc)) of 9.26 mA.cm(-2), open-circuit voltage (V-oc) of 0.835 V and fill factor (FP) 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%).
