Synthesis and Characterization of Zinc Oxide Nanoparticles by Electrochemical Method for Environmentally Friendly Dye-Sensitized Solar Cell Applications (DSSCs)

Abstract

In this research, zinc oxide nanoparticles (ZnO NPs) were made utilizing an electrochemical method. Which has the advantages of being quick, simple, producing no side products, and being inexpensive. Advanced techniques such as x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis), energy dispersive x-ray (EDX), and atomic force microscopy (AFM) were used to characterize the generated zinc oxide. Using methyl orange dye, the analysis showed that the shape of zinc oxide nanoparticles was rice-like and the band gap value was 3.62. ZnO NPs is used in dye-sensitized solar cells (DSSCs) it has many advantages including its ease of use and low cost, its ability to be integrated into buildings, and its fantastic performance under diffuse and indoor lighting. DSSCs have attracted more attention and have been deemed viable alternatives to conventional photovoltaic devices. The solar cell's efficiency (η %) and fill factor with methyl orange as a dye were 2.3, and 74.1, respectively.
