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.
