通过两步法,即首先热分解醋酸锌制备氧化锌晶种层,在晶种的诱导下,再采用低温水热法在氟掺杂的SnO_2导电玻璃(fluorine-doped tin oxide,FTO)基底导电面上成功制备出高取向性的氧化锌纳米棒阵列光电极.系统研究了前驱液浓度、溶液pH值、反应时间等实验条件对光电极微结构的影响.实验结果表明在一定变化范围内,随着前驱液浓度和溶液pH值的增大,纳米棒的直径增大;随着反应时间的延长,纳米棒的长度增长.将氧化锌纳米棒阵列薄膜制作成染料敏化太阳电池(dve-sensitizedsolar cell,DSSC)的光电极,并对电池的,I-V特性进行了表征.

Highly oriented nanorod arrays of ZnO were grown by the hydrothermal method at low temperature on the conductive side of the FTO(fluorine-doped tin oxide) where ZnO seeds had been fabricated by the decomposition of Zn(Ac)_2. The effects of the reaction conditions such as solution concentration, pH value and reaction time upon the microstructures of the nanorod arrays were studied. The results show that the diameter of nanorods increases with the increase in solution concentration and pH value, respectively. The length of nanorods increases as reaction time increases. The films of ZnO nanorod arrays were used and characterized as the photoelectrode of DSSC (dye sensitized solar cells).
