Photovoltaic (PV) power generation is a clean energy source, and the accumulation of ash on the surface of PV panels can lead to power loss. For polycrystalline PV panels, self-cleaning film is an economical and excellent solution.
The self-cleaning coating has attracted extensive attention in the photovoltaic industry and the scientific community because of its unique mechanism and high adaptability. Therefore, an efficient and stable self-cleaning coating is necessary to protect the cover glass on the photovoltaic panel. There are many self-cleaning phenomena in nature.
When sunlight shines on the photovoltaic panel, part of the visible light will be reflected, and the rest will be converted and utilized. Therefore, the transparency and anti-reflection of the self-cleaning coatings applied on photovoltaic modules cannot be ignored.
