Abstract

Scientific research is advancing rapidly to enhance solar cell efficiency as an alternative to fossil fuels, which cause significant environmental damage. This study focuses on two key strategies: first, the synthesis of zinc oxide nanoparticles (ZnO NPs) using electrochemical methods due to their simplicity, speed, and cost-effectiveness; and second, utilizing ZnO as a highly efficient luminescent solar concentrator (LSC). X-ray diffraction (XRD) and transmission electron microscopy (TEM) confirmed the formation of ZnO nanorods and spherical particles. Additionally, fluorescein sodium dye was incorporated to enhance solar cell efficiency. fluorescein sodium dye and zinc oxide nanoparticles were mixed in volume ratios.The combination of 50% ZnO with fluorescein sodium dye resulted in an efficiency increase of 33.75%, whereas the standalone dye application yielded an efficiency of 25.97%. These findings represent significant progress in the pursuit of clean, efficient, and sustainable energy solutions, demonstrating the potential of nanotechnology and innovative dye applications in improving solar cell performance and mitigating environmental impact.
