Green Synthesis of Ashwagandha- Derived Nanomaterials for Advanced Solar panel Applications

Abstract

Green nanotechnology offers a sustainable and environmentally friendly pathway for developing functional nanomaterials without the use of hazardous chemicals or energy-intensive procedures. This study introduces a novel method for synthesizing titanium dioxide (TiO₂) nanoparticles using an aqueous extract of Withania somnifera (Ashwagandha), a medicinal plant known for its rich phytochemical content. The biosynthesized TiO₂ nanoparticles were characterized through UV-Vis spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM), which confirmed their crystalline structure and uniform morphology. These nanoparticles were incorporated into solar panel systems to enhance light absorption and improve overall photovoltaic performance. The integration of Ashwagandha-derived TiO₂ resulted in improved charge separation and a noticeable boost in power conversion efficiency. This green synthesis strategy highlights the potential of plant-based nanomaterials in advancing sustainable solar technologies while minimizing environmental impact.
