Structure nanoflower technique spray coating has been successfully carried out. ZnO nanoflower can improve the performance of photo-supercapacitor because it is more effective in light absorption. In this study, Dye-Sensitized Solar Cell (DSSC) was fabricated from ZnO nanoflower using a spray coating combined with TiO2 as a photoanode, while the supercapacitor was fabricated from BaTiO3. Variations in pressure and size of spray coating are used to determine their effect on photo-supercapacitor performance. The results of XRD analysis showed that the greater the pressure and the size of the spray, the greater of crystallinity and the size of the crystal particles. The results of SEM analysis showed that the ZnO nanoflower formed at a pressure of 5 bar with the highest porosity of 0.79. The effect of pressure and spray ZnO nanoflower on photo-supercapacitor performance was investigated by UV-vis characterization. In addition, by using the solar simulator test, the DSSC efficiency of 7.02% was obtained. Supercapacitors that function as energy stores in photo-supercapacitors. Charge discharge show that the supercapacitor has a specific capacitance of 29.20 F/g. Technique spray coating succeeded in forming ZnO nanoflower and increasing the photo-supercapacitor performance. © 2025 American Institute of Physics Inc.. All rights reserved.
