以商用金红石相TiO2粉末为原料,通过在碱性溶液中150℃水热48 h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30 min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,两者之间灌入液态电解质,电池的有效面积为0.28 cm2.在标准氙灯模拟器下(AM1.5,100 mW/cm2)测试了电池的J-V特性,得到2.17%的光电转换效率.
The TiO2 nanotubes were synthesized by commercial rutile TiO2 powders by hydrothermal treatment at 150 ℃ for 48 h in alkaline solution.The morphologies and structure evolution of TiO2 nanotubes were characterized by SEM, TEM and XRD. The prepared TiO2 nanotubes were mixed with Triton X-100 and acetylacetone and then applied to an ITO conductive glass substrate by a screen printing method and sintered at 450 ° C. for 30 min to obtain a dye-sensitized solar cell Of the porous photoanode. The photoanode soaked in N719 dye sensitization, and platinum-plated counter electrode assembly battery, liquid electrolyte between the two, the effective area of the battery is 0.28 cm2 in a standard xenon lamp simulator (AM1 .5,100 mW / cm2) The JV characteristics of the battery were tested to obtain a photoelectric conversion efficiency of 2.17%.
