| 摘 要： | 采用十二烷基苯磺酸钠表面活性剂(DBS)辅助水热法合成TiO2纳米材料,XRD和TEM测试表明,不含DBS的TiO2溶胶水热处理后得到10~20nm锐钛矿型TiO2纳米颗粒;添加DBS后,生成了金红石型TiO2纳米棒.虽然金红石型TiO2纳米棒光电极的染料吸附性能和光电性能均不如锐钛矿型TiO2纳米颗粒光电极,但金红石型TiO2纳米棒漫反射性能较高.可用其制备具有光电转换性能的反射层,这种新型反射层使染料敏化太阳能电池光电转换效率提高了26.14%,而含Ti-nanoxide 300大颗粒TiO2构成的反射层仅能使电池光电转换效率提高11.04%.这种差异的根源在于金红石型TiO2纳米棒不仅具有散射光能力,其本身还可吸附染料进行光电转换.随着反射层厚度的增加,电池短路电流逐步提高.而不吸附染料且无光电转换能力的Ti-nanoxide 300传统反射层则没有这种功能.

| Abstract: | The sodium dodecyl benzene sulfate(DBS) surfactant was used in the hydrothermal synthesis of TiO2 nanomaterials.Without the addition of DBS in the TiO2 Sol,the obtained sample is 10-20nm anatase TiO2 nanoparticle.While with the addition of DBS,the obtained sample turns to rutile TiO2 nanorod.Although the dye adsorption ability and the photovoltaic performance of the photoelectrode with rutile TiO2 nanorod is poorer than that of the photoelec-trode with anatase TiO2 nanoparticle,the rutile TiO2 nanorod has h... |
