Which surface treatment is suitable for preparing photovoltaic self-cleaning surfaces?

CVD-based surface treatment is suitable for preparing photovoltaic self-cleaning surfaces. These methods prepare self-cleaning surfaces by reacting gaseous substances with hot surfaces and depositing them on the surface. They are efficient but difficult to control accuracy.

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.

Can SIO 2 nanoparticles adhere to micro-PVDF protrusions?

In addition, through the modification of epoxy siloxane copolymer, SiO 2 nanoparticles can adhere to the surface of micro-PVDF protrusions. Through the underwater immersion test, it is found that SiO 2 nanoparticles are not easy to separate from PVDF and have good durability.

How to clean photovoltaic panels based on CVD?

There are many methods based on CVD, and they are widely used in the self-cleaning of photovoltaic panels. But in general, such methods are not easy to control the accuracy. As a relatively simple method, the sol–gel method has low cost, few technical details, and is environmentally friendly.

What substrates are suitable for ZnO hydrophobic coating?

(24) The ZnO hydrophobic coating was prepared on borosilicate glass, amorphous quartz, single-crystal sapphire, lanthanum aluminate, and yttria-stabilized zirconia substrates using thermal evaporation methods, (22) which are also suitable for mechanical and oxidation resistance applications.

What is a water contact angle in PV glass?

Year-wise articles published of self-cleaning PV glass (Data Source Web of Science) After the liquid droplet is on the solid surface, there is an included angle between the solid–liquid interface and the gas–liquid interface, which is called the water contact angle (WCA).
