In this study, the influence of the seed-layer thickness of photoelectrodes on the performance of dye-sensitized solar cells was investigated. Al-doped ZnO films deposited on fluorine-doped tin oxide substrates by using facing targets sputtering systems of various thicknesses were used as seed layers, and ZnO rod array photoelectrodes were synthesized on the AZO seed layers via the hydrothermal process. The crystallinity of the ZnO photoelectrode was improved, and the average diameter of the ZnO rod increased from 100 ± 10 to 250 ± 10 nm as the thickness of the seed layer increased from 200 to 600 nm. The maximum fill factor, open-circuit voltage, current density, and power conversion efficiency of the ZnO rod array photoelectrode with a seed layer of thickness 600 nm were 31.08%, 0.53 V, 5.53 mA/cm2, and 0.91%, respectively.

染料敏化太阳能电池氧化锌光电极的优化

在这项研究中，研究了光电极种子层厚度对染料敏化太阳能电池性能的影响。使用不同厚度的正对靶溅射系统在掺氟氧化锡衬底上沉积的掺铝 ZnO 薄膜用作种子层，并通过水热工艺在 AZO 种子层上合成 ZnO 棒阵列光电极。ZnO 光电极的结晶度得到提高，随着籽晶层厚度从 200 nm 增加到 600 nm，ZnO 棒的平均直径从 100±10 nm 增加到 250±10 nm。种子层厚度为 600 nm 的 ZnO 棒阵列光电极的最大填充因子、开路电压、电流密度和功率转换效率分别为 31.08%、0.53 V、5.53 mA/cm2 和 0.91%。
