Hydrothermal Synthesis of Rutile TiO2 Bottle Brush for Efficient Dye Sensitized Solar Cells |
초록 |
Hydrothermal process has been employed to synthesize titanium oxide (TiO2) bottle brush. The nanostructured bottle brush like morphology was obtained merely by changing the nature of the precursors and hydrothermal processing parameters. The influence of such nanostructures on the performance of dye sensitized solar cells (DSSCs) is investigated in detail. Surface area of samples wasrecorded using Brunauer-Emmett-Teller(BET) measurements. It is found that bottle brush provides effective large surface area 89.34 m²/g which is much higher than TiO2 nanorods 63.7 m2/g. Such effective surface area can facilitate the effective light harvesting, and hence improves the dye adsorption and the photovoltaic performance of DSSCs, typically in short-circuit photocurrent and power conversion efficiency. A best power conversion efficiency of 6.63 % has been achieved. We believe that the present device performance would have wide interests in dye sensitized solar cell research. |
