The photoelectrical properties of thylakoid membrane from two plants fabricated on Nano-ZnO
两种植物类囊体膜在纳米ZnO 上的组装和光电性质

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.
