| 摘 要： | 通过二次水热法合成锐钛矿TiO2纳米棒(ANR). 采用X射线衍射(XRD)、场发射扫描电镜(FE-SEM)和透射电镜(TEM)等手段对其进行表征. 通过调节ANR和锐钛矿纳米颗粒(ANP)的掺杂比例来增加TiO2纳米晶膜的光捕获效率和电子传输速率, 并对比了单层结构(ANR+ANP)和双层结构(ANP/(ANR+ANP))的纳米晶膜光阳极的光电转化性能. 在AM 1.5、光强100 mW·cm-2的模拟太阳光下测试, 染料N719敏化的双层结构太阳能电池光电转化效率达7.3%, 比相同条件下单层纯ANP光阳极器件的光电转化效率(6.1%)提高了20%.

| Abstract: | TiO_2 anatase nanorods(ANR) were synthesized by a two-step hydrothermal method.The materials were characterized by X-ray diffraction(XRD),field emission scanning electron microscopy (FE-SEM),and transmission electron microscopy(TEM).To increase the light harvesting efficiency and electron transfer rate,N719 dye-sensitized solar cells(DSSCs) were constructed and compared by adjusting the doping ratio of the anatase nanoparticles(ANP) and ANR in the TiO_2 nanocrystalline film that was used as a photoanode in ... |
