采用化学水浴法制备Al掺杂的ZnO纳米棒阵列,研究其在染料敏化太阳能电池中的性能。X射线分析和X射线光电子能谱分析表明:Al成功掺入ZnO晶格内;ZnO:Al具有六方纤锌矿型结构;少量的Al掺杂并没有引起ZnO晶体结构的变化。利用线性伏安扫描得到电池的伏安曲线表明Al掺杂ZnO纳米结构能够提高电池的光电转换效率η。当前驱体溶液中Zn源的初始浓度为0.01mol/L时,制备的掺5%Al的ZnO薄膜染料敏化太阳能电池的η为0.42%,与未掺杂的ZnO电池相比,其光电转换率提高明显。
Al-doped ZnO nanorod arrays were prepared by chemical bath method and their properties were studied in dye-sensitized solar cells. X-ray analysis and X-ray photoelectron spectroscopy analysis showed that Al was successfully incorporated into the lattice of ZnO. ZnO: Al had hexagonal wurtzite structure. Small amount of Al doping did not change the crystal structure of ZnO. The voltammetry curve of the battery obtained by linear voltammetry scan shows that the Al-doped ZnO nanostructures can improve the photoelectric conversion efficiency η of the battery. When the initial concentration of Zn source in the precursor solution is 0.01 mol / L, the η of the prepared 5% Al-doped ZnO thin film dye-sensitized solar cell is 0.42%. Compared with the undoped ZnO cell, the photoelectric conversion Rate increased significantly.
