Transparent, superhydrophilic materials are indispensable for their self-cleaning function, which has become an increasingly popular research topic, particularly in photovoltaic (PV) applications. Here, we report hydrophilic
The majority of solar panel manufacturers test and certify their products to withstand hail up to one inch in diameter falling at 50 miles per hour. Solar panels today are also extremely resistant to high winds and heavy rain. The majority
The solar panel durability depends on the materials used for the solar panel and framing. Certain types of resilient plastic are used to protect solar cells from dust and moisture. For example, ETFE plastic is a standard in high
It strictly suggests the need to balance the three parameters of anti-soiling, transparency, and durability of these films for their effective use. The transparency and superhydrophobicity of the PV panels are already competitive enough and get even compromised by considering durability.
Many research articles were reported on the superhydrophobicity as well as anti-reflective coatings [2, 3, 7, 22]. Also, there is a few research on the SH-AR materials for solar panels [23, 24]. However, they have not covered the durability of the system, which is one of the main concerns from a commercial point of view.
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.
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.
In this work, commercial solar panels were coated with sparked titanium films, and the antireflective, super-hydrophilic, and photocatalytic properties of the films were investigated. The reflectance, photocatalytic properties, and degradation of the organic pollutant methylene blue were determined using UV–Vis spectroscopy.
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.
