  • 以商用金红石相TiO2粉末为原料,通过在碱性溶液中150℃水热48h的方法合成TiO2纳米管.采用SEM,TEM,XRD分析手段对TiO2纳米管的形貌和结构演变进行了表征.制成的TiO2纳米管与TritonX-100,乙酰丙酮混合后,通过丝网印刷的方法涂敷到ITO导电玻璃衬底上,并且在450℃下烧结30min后得到可应用于染料敏化太阳电池的多孔光阳极.将此光阳极浸泡于N719染料敏化后,与镀铂对电极组装电池,两者之间灌
    TiO2 nanotubes were synthesized from commercial rutile powder by means of the hydrothermal method in alkaline solution at temperature of 150℃ for 48hours. The morphology and structure evolutions were characterized with SEM,TEM and X-ray diffraction. The TiO2 nanotubes mixed with Triton X-100 and acetyl acetone were screen-printed onto the glass substrate coated with a transparent conducting oxide (ITO,or tin-doped indium oxide),then sintered at 450℃ for 30 minutes to form porous photoanode of dye-sensitized solar cells. A solar cell withactive area of 0.28cm2 was assembled with N719-coated nanotube-TiO2 electrode,Pt-coated ITO glass and iodide-based ionic liquid electrolyte. The J-V curve was measured using a standard solar simulator (AM1.5 spectrum,100mW/cm2),and a photoelectric conversion efficiency of 2.17% was obtained.
