Étude et réalisation de Couches Minces biosourcés Hydrophobes et Anti-Poussière pour les surfaces vitrées des panneaux solaires photovoltaïques

Abstract

This study falls within the scope of applied research at the intersection of advanced materials, environmental sustainability, and surface functionalization. It contributes to the development of clean technologies by exploring environmentally responsible solutions based on renewable natural resources in the field of functional coatings. The adopted approach aims to balance technical performance with adherence to green chemistry principles, targeting high-value applications in energy systems and material protection. The research focuses on the development and characterization of bio-based thin films exhibiting hydrophobic and dust-repellent properties. Natural components, including essential oils, green solvents, and biopolymers, were selected for their ecological compatibility, surface functionality, and optical stability. The coatings were applied using the dip-coating method—a simple, reproducible technique capable of producing uniform and homogeneous films.

Characterization techniques included UV-Visible spectrophotometry to assess optical transparency and Atomic Force Microscopy (AFM) for surface morphology analysis. The results revealed good light transmittance, controlled surface roughness, and satisfactory hydrophobic performance. This work proposes a viable ecological alternative to conventional coatings for dusty environments and opens promising prospects for optimizing bio-sourced materials in photovoltaic applications.
