| 摘 要： | 采用水热法制备了TiO2和CdSe两种纳米棒材料, 将两种纳米材料制备成TiO2/CdSe复合纳米棒膜电极, 并在复合膜上电化学聚合生成聚3-甲基噻吩poly(3-methylthiophene) (PMeT), 研究了其光电化学性能. 实验表明, 当TiO2与CdSe的物质的量复合比为2∶1, PMeT的聚合时间为40 s, 在电极电势为－0.2 V下ITO/TiO2/CdSe/PMeT电极光电转换效率(IPCE)达到56%, 对比ITO/TiO2/CdSe复合膜电极在长波方向的光电转换效率明显提高, 光吸收截止波长发生了明显的红移. 同时以ITO/TiO2/CdSe/PMeT组装了简易的杂化太阳电池, 初步研究了光电池性能, 光电池总效率为0.08%, Voc＝0.4 V, jsc＝0.61 mA/cm2, ff＝0.33. |

| Abstract: | TiO2 and CdSe nanorods were prepared by a hydrothermal method. The photoelectrochemical properties of TiO2/CdSe composite film and TiO2/CdSe/PMeT film were investigated. The experiment results showed that the incident photon to current conversion efficiency (IPCE) of TiO2/CdSe/PMeT was obviously increased in comparison to that of TiO2/CdSe composite film. The experiment results showed that the p-n heterojunction existed in the TiO2/CdSe/PMeT nanostructure film, which favored the separation of electron-hole pairs generated by photoexcitation. The IPCE value of TiO2/CdSe/PMeT film was 56% at －0.2 V, and the incident light wavelength of 370 nm. The hybrid solar cell was fabricated with TiO2/CdSe nanostructure composite film and poly(3-methylthiophene) (PMeT). The conversion efficiency of the hybrid solar cell was 0.08%, short current 0.61 mA/cm2, open voltage 0.4 V, fill factor 0.33, under irradiation of 100 mW/cm2 white light from a Xe lamp. |
