| 摘 要： | 用水热合成法在掺氟氧化锡(SnO2: F, FTO)导电玻璃上合成了ZnO 纳米线并用原子力显微镜(AFM)和扫描电镜(SEM)对其进行了表征。利用LB 膜技术将高等植物菠菜(Spinacia oleracea)和海洋绿藻石莼(Ulva lactuca)的类囊体膜分别固定在纳米ZnO 上组装成光电池, 用太阳能测试系统检测比较了其光电性质。研究表明, 由两种植物的类囊体膜LB 膜组成的光电池都能产生光生电流; 蛋白LB 膜的层数显著影响了光电池的光电转化效率, 随着层数的增加, 光电转化效率大大增加。此外, 石莼类囊体膜组装的光电池光电转化效率明显高于菠菜类囊体膜。

| Abstract: | ZnO nanowires were synthesized on the FTO glass by hydrothermal method and characterized by atomic force microscopy (AFM) and scanning electron microscopy (SEM). Thylakoid membranes isolated from higher plant spinach and marine green alga Ulva lactuca were fabricated on the ZnO nanowires by using Langmuir Blodgett (LB) technique. The photoelectrical properties of these two resulting systems were assessed and compared by solar cell test system. Photocurrents were both observed the solar cells containing the LB films of the thylakoid membranes of these two plants. The photoelectric conversion efficiencies of solar cells were increased significantly with the numbers of LB film layer. In addition, the photoelectric conversion efficiency of cell containingUlva thylakoid membrane was much higher than that of spinach. |
