Why do photovoltaic panels need a self-cleaning coating?
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.
Why do photovoltaic panels need a transparent coating?
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.
What happens if dust is deposited on Photovoltaic Glass?
In addition, dust deposition will also cause damage to the coating applied to the photovoltaic glass. Goossens and Van Kerschaever (1999) reported that the fine dust deposited on the photovoltaic glass causes permanent damage to the anti-reflection coating.
What does the photocatalytic coating do to the solar panel surface?
The photocatalytic coating provokes self-cleaning of the panel surface by utilizing the incident solar irradiation. This approach aims to increase the efficiency of photovoltaic (PV) panels.
Does solar photovoltaic panel cover glass have a natural reflectance?
Although solar photovoltaic panel cover glass is highly transparent, it has a natural reflectance in the visible wavelength range. An effective method to increase the effectiveness is to reduce the optical loss and natural reflectance via antireflection (AR) coatings.
What is self-cleaning coating on solar cell glass?
In 2016, Xu et al. have invented the self-cleaning coating on solar cell glass by using spin-coating and reactive ion etching. The prepared superhydrophobic self-cleaning coating possesses WCA around 154° and optical transmission coating around 88% in the wavelength of 300−800 nm.
