Dye-Sensitized Solar Cell (DSSC) is a device that converts sunlight energy into electrical energy with a higher efficiency than the previous generation with the use of dyes. Photoanode, as a component in the DSSC system, plays a role in the absorption of molecules with high surface area and electron conductors excited by dyes. The photoanode semiconductor material that is often used is Zinc Oxide (ZnO) which has several advantages including low price, ease of synthesis, and high electron mobility is attracting attention because it has a piezo-tronic effect and a piezo-phototronic effect that can modulate migration and separate charge carriers which enhances photocatalytic performance. The effect of hexagonal wurtzite structure, height, diameter, and porosity of ZnO nanorod has the potential to improve the performance of DSSC. ZnO has characteristics suitable for the sensitization of organic dyes, rather than metal dyes because absorption is increased by the presence of electron donors in metal-free organic dyes. Organic dye exhibits interesting spectral characteristics and electrochemical mechanisms through the contribution of molecular precision to ZnO nanorods photoanode. High porosity affects the increase in dye absorption and a low energy gap to increase the electron excitation rate. The absorption enhancement and optimized energy gap of the ZnO nanorod structure with organic dyes enhance the performance of DSSC. Therefore, in this paper, the best photovoltaic performance is studied in more detail to determine the effect of organic dyes on the performance of ZnO nanorod-based DSSC. © 2025 American Institute of Physics Inc..
