Enhancing Photovoltaic Efficiency of Porous Silicon Solar Cells with Copper Oxide Nanoparticle Anti-Reflective Coatings

Innovation in photovoltaic technology is driven by the search for sustainable and effective energy production. In this study, we investigate how Anti-Reflective Coatings (ARCs) made of copper oxide nanoparticles (CuO NPs) might be integrated into Porous Silicon (PS) solar cells to increase photovoltaic efficiency. The main goal is to reduce incident sunlight loss from reflection, which will increase light absorption and energy conversion. Colloidal nanoparticles, or CuO NPs, were synthesized via the electrolysis process and coated onto glass substrates and p-type PS to create films through the use of the spin coating method. The Electrochemical Etching process (ECE) is used to prepare PS. X-ray Diffraction (XRD) and an Atomic Force Microscope (AFM) have been used to study the structural and morphological properties of copper oxide nanostructures (CuO NSs) that have b
