 摘要：采用水浴法制备了不同掺杂浓度(Al3+和Zn2+物质的量比为0、1%、3%和5%)的ZnO：Al纳米柱阵列，通过扫描电子显微镜(SEM)、X-射线衍射仪(XRD)、X射线能谱仪(EDS)等手段对样品进行了表征。测试结果表明：制备的纳米柱阵列结晶性好、具有c轴取向生长特性，能谱显示Al元素成功掺入ZnO纳米柱阵列中。通过紫外可见吸收光谱和表面电阻测试发现：掺杂后，纳米柱阵列光透过率提高且表面方块电阻下降。将ZnO：Al纳米柱阵列作为电子传输层应用于钙钛矿太阳能电池器件中，在低掺杂浓度(1%)时得到最佳器件性能，光转化效率达到5.78%，相比较未掺杂ZnO纳米柱阵列，开路电压和短路电流均有提高，光转化效率提高了48%。

 Abstract: ZnO：Al nanorods array with different Al3+ doping concentrations of 0, 1%, 3% and 5% were prepared by water bath method. The morphology and crystalline structure of ZnO：Al nanorods array were characterized by SEM, XRD and EDS. The optical and electrical properties are researched by UVvis and square resistance. The analysis indicates that the ZnO nanorods are orderly arrayed with good crystallinity. EDS shows that Al doped into ZnO：Al nanorods array successfully. After doping Al3+, ZnO nanorods transmittance improved and the surface square resistance droped. ZnO：Al nanorods array are incorporated in the organic solid perovskite solar cells as electron transporting layer. The optimized device (at lower doping of 1%) show a power conversion efficiency of 5.78%, which is 48% higher than the device without Al doping. The open circuit voltage and short circuit current are improved compared with the bare ZnO based device.

 Key words: Al3+ doping; ZnO; nanorods array; perovskite; solar cells
