采用化学浴沉积法（CBD）和水热法（HTM）制备了ZnO纳米棒阵列。研究了ZnO纳米阵列作为光电极在染料敏化太阳能电池（dsc）中的光电性能。实验结果表明，溶胶-金法制备的ZnO种子晶体具有c轴取向，由50~100nm范围内的纳米颗粒组成。在种子晶层上生长的ZnO纳米阵列中，保持了相同的粒径和取向。基于ZnO纳米阵列的dsc作为光电极，由于ZnO与染料之间的吸附结合力较弱，染料吸附量较低，光伏性能较差。相比之下，水热法制备的由ZnO阵列组成的dsc性能最佳，其短路光电流密度（Jsc）、开路电压（Voc）、填充系数（FF）和光电转换效率（η）分别为4.89 mA/cm2、0.650V、0.39%和1.25%。
ZnO nanorod arrays were successfully prepared by chemical bath deposition (CBD) and hydrothermal method (HTM), respectively. The photovoltaic performance of ZnO nanoarrays as photoelectrodes in dye-sensitized solar cells (DSCs) was investigated. Experimental results show that ZnO seed crystals prepared by a sol-gol process have c axis orientation and consist of nanoparticles within the range of 50~100nm. The same particle size and orientation is well preserved in ZnO nanoarrays grown on the seed crystal layers. The photovoltaic performance of DSCs based on ZnO nanoarrays as the photoelectrodes is poor, due to the weaker adsorption bond force between ZnO and dye, and lower dye adsorption quantity. By contrast, the DSCs composed of ZnO arrays prepared by hydrothermal method have optimal performance, the corresponding short circuit photocurrent density (Jsc), open circuit voltage (Voc), fill factor (FF) and photoelectric conversion efficiency (η) are 4.89 mA/cm2, 0.650V, 0.39 and 1.25 %, respectively.
