本研究使用摻氟氧化錫(FTO)為透明導電基板，FTO基板相較於氧化銦錫(ITO)基板而言在高溫退火下有較佳的耐熱性，使性能較不易衰退。以奈米球旋塗在氧化鋅晶種層上，並以鹽酸進行蝕刻，來達到圖案化區域層和控制氧化鋅奈米柱生成區域，藉由改變氧化鋅奈米柱的生成時間，可以使氧化鋅奈米柱具有不同粗細尺寸奈米柱，細長氧化鋅奈米柱可以增加吸收表面積、粗長的氧化鋅奈米柱可以提升電子傳遞。
經過分析，在二氧化鈦緻密層厚度為3微米之條件下微米球控制生長分布在經由
1至5小時的氧化鋅奈米柱生長後，發現在3小時生長的氧化鋅奈米柱有得到電池效率最高，同時具有最高的IPCE及UV-Vis特性曲線，在效率方面，生長時間為3小時有較佳的效率為0.080%,。而在 EIS 的部分，可以發現生長時間為3小時 內部電阻有較小的阻抗。

In this study, fluorine-doped tin oxide (FTO) was used as a transparent conductive substrate. Compared with an indium tin oxide (ITO) substrate, the FTO substrate has better heat resistance under high temperature annealing, which makes the performance less susceptible to degradation. The nanosphere is spin-coated on the zinc oxide seed layer and etched with hydrochloric acid to reach the patterned region layer and control the zinc oxide micro-pillar formation region, and the oxidation time can be made by changing the generation time of the zinc oxide nano column. Zinc micron columns have different sizes of micron columns, elongated zinc oxide micron columns can increase the absorption surface area, and thick zinc oxide micron columns can enhance electron transport.
After analysis, the nanospheres controlled the growth distribution under the condition that the thickness of the dense layer of titanium dioxide was 3 micrometers. After growth of the zinc oxide nanometer column through 1 to 5 hours, it was found that the zinc oxide nano column grown at 3 hours had the highest battery efficiency. At the same time, it has the highest IPCE and UV-Vis characteristic curve. In terms of efficiency, the growth time is 3 hours and the better efficiency is 0.080%. In the EIS section, it can be found that the growth time is 3 hours and the internal resistance has a small impedance.
