有 20 wt.% 的 DWCNTs/TiO2 的钛 dioxide-double-walled 碳 nanotubes (TiO2-DWCNTs ) 被一个常规大音阶的第五音胶化方法准备。在 TiO2 photoanode 做 TiO2-DWCNTs,一节灵活敏化染料的太阳能电池(DSSC ) 被制作。样品被扫描电子显微镜学描绘, X 光检查衍射(XRD ) , Fourier 变换红外线的光谱学(FTIR ) 吸收,紫外可见的光谱学(UVvis ) 吸收系列,电气化学的阻抗光谱学(EIS ) 技术和光电的测量。它被发现那补充说 TiO2-DWCNTs 的某个数量能高效地减少费用运输的抵抗,改善染料吸附。在一个最佳的条件下面,灵活 DSSC 与 0.50 wt.% TiO2-DWCNTs 包含了完成 3.89% 的 light-to-electric 精力变换效率在下面一 simulate 100mWparency 的太阳的轻照耀吗??
Titanium dioxide-double-walled carbon nano- tubes (TiO2-DWCNTs) with DWCNTs/TiO2 of 20 wt.% is prepared by a conventional sol-gel method. Doping the TiO2-DWCNTs in TiO2 photoanode, a flexible dye- sensitized solar cell (DSSC) is fabricated. The sample is characterized by scanning electron microscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) absorption, ultraviolet-visible spectroscopy (UV- vis) absorption spectra , electrochemical impedance spec- troscopy (EIS) technique and photovoltaic measurement. It is found that adding a certain amount of TiO2-DWCNTs can efficiently decrease the resistance of charge transport, improve dye adsorption. Under an optimal condition, a flexible DSSC contained with 0.50 wt.% TiOz-DWCNTs achieves a light-to-electric energy conversion efficiency of 3.89% under a simulate solar light irradiation of 100 mW. cm^2.
