Synthesis of Aluminum Oxide Nanoparticles and Their Applications in Dye-Sensitized Solar Cells as a Clean Energy

Abstract

In this research, the aluminum oxide nanoparticles (Al2O3 NPs) were prepared using electrochemical method. The Features of the electrochemical process are ease and speed, free side product, and economical. The prepared aluminum oxide was characterized using many techniques like x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), ultra violate – visible (UV-Vis), energy dispersive x-ray (EDX), and atomic force microscopy (AFM). The shape of the prepared aluminum oxide was in the form of nanowire and has an energy gap of 3.9. Since fossil fuels are rapidly running out and their consumption increases the average global temperature, which has an impact on human life, the energy crisis is the main global concern. Consequently, in order to generate energy, dye sensitized solar cells (DSSCs) must be produced. The results indicate that the efficiency (η %) of the solar cell using methyl orange as a dye and fill factor were 1.17 and 56.8, respectively.
