Enhancing photovoltaic efficiency with self-cleaning titanium dioxide nanoparticle coatings: a sustainability approach

This paper explores the use of self-dispersing TiO₂ nanoparticles for enhancing photovoltaic efficiency through self-cleaning coatings. These coatings reduce dust accumulation on solar panels, demonstrated by a 5% increase in electricity generation, thereby improving sustainability and reducing maintenance needs. The TiO₂ nanoparticles, synthesized with self-dispersing properties, were characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM) to analyze their crystal structure and surface morphology. The findings demonstrate that these nanoparticles possess notable photocatalytic properties, enabling the degradation of organic pollutants under ultraviolet light. Furthermore, measurements of coating transparency and contact angle confirmed that the coating not only maintains high transparency but also exhibits excellent self-cleaning performance. Overall, the application of TiO₂ nanoparticle coatings effectively reduces the maintenance requirements of solar panels, enhancing the sustainability and economic viability of photovoltaic systems.
