摘　　要：用射频溅射法在透明导电玻璃上分别沉积了氧化锌（ZnO）和掺铝氧化锌（AZO）薄膜，其可见光透射率达到85％以上。用水热法在不同的薄膜作种子层的导电玻璃上生长了纳米棒，x射线衍射分析（XRD）发现所制得的纳米棒都有（002）择优取向；扫描电子显微镜（SEM）结果表明，采用不同的实验条件和参数可以有效的影响纳米棒的长度、直径、密度等，并得到了垂直于衬底的纳米结构。用所得到的纳米结构制作太阳能电池的效率达到了0．26％。ZnO and ZnO：AI（AZO） films on transparent conductive glass were prepared by radio frequency magnetron sputtering. Transmittance above 85% at visible light region was achieved. The hydrothermal method was been employed to synthesis nanorods on the films. X-ray diffracation shows the nanorods are single crystal with c-axis （002） preferred orientation. The scanning electron microscopy （SEM） images illuminated that the seed layers have great influence on the morphology of the nanorods. Vertically aligned ZnO nanorods were synthesized. A photo-voltage conversion efficiency of 0.26% of the dye sensitized solar cell with as prepared nanorods was achieved.
