Studying the Optical and Morphology Properties of PMMA and Batio₃/Sb ₂ O₃ PMMA Hybrid Nanoparticles Coatings Doped for Application Coatings Solar Cells and Electronic Screen

Abstract This article primarily aims to define the parameters related to the optical and morphological properties of solvent-cast and spun-spun coatings for coatings that offer protection against environmental conditions. It also seeks to better understand how to control the morphology and properties of coated thin films used in high-performance polymer solar cells and electronic displays to meet the protection requirements of these coatings in the aforementioned applications. This composite nano coating promotes sustainability in various ways. It increases the energy efficiency of electronic displays and solar cells, thus reducing consumption and the carbon footprint. It also enhances the durability and stability of solar cells and electronics, extending their lifespan and directly reducing electronic waste. The hybrid coating layer improves light absorption, thereby increasing the efficiency of solar and electronic cell coatings while simultaneously providing environmental protection. With increased efficiency of the hybrid materials, the efficiency of solar cells can be further improved. Hybridizing poly methyl methacrylate (PMMA) with barium titanate/antimony dioxide (BaTiO 3 /3) via solvent casting or spin coating enhances its properties, resulting in thin nanocomposites. UV-Vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM) were used to investigate the materials used to improve coatings for solar cells and electronic displays. The energy gap between the BaTiO 3 /Sb 2 O 3 nanoparticles decreased (from 2.4 eV for pure PMMA nanoparticles to 2 eV for PMMA nanoparticles at a concentration of 2.7 wt.%), indicating improved infrared shielding. Scanning electron microscopy revealed that the nanoparticles are homogeneously distributed, allowing for load transfer and dispersion at low concentrations (0. 9 –2. 7 %), with some agglomeration occurring at 2.7%. Infrared spectroscopy revealed physical bonds (hydrogen bonds/dipole interactions) between the nanoparticles and the PMMA material, with no chemical bonds present. The unique structure and optical properties of the nanocomposites suggest their potential for developing protective coatings with enhanced properties. Anti-reflective treatment was achieved using a simple spin-coating method based on solvent casting, resulting in a significant increase in the reflectance coefficient and the incident photon-to-electron conversion efficiency to approximately 100 electrons in the visible spectrum. Our results demonstrate significant potential for developing high-efficiency hybrid solar cell coatings and electronic coatings, as well as hybrid nanoparticle structures, which are of considerable research interest.
