What is the surface coating of photovoltaic panels
The variance in dust density from point to point raises the risk of forming hot spots. Therefore, a prepared PDMS/SiO2 nanocoating was used to reduce the accumulated dust on the PV panels'.

Here, we report hydrophilic and superhydrophilic ZnO by varying the morphology for use as a self-cleaning coating for PV applications. Three different ZnO microstructures, such as ZnO nanorods (R-ZnO), ZnO microflowers (F-ZnO), and ZnO microspheres (M-ZnO), were developed by hydrothermal methods.
It is essential that AR coatings are applied to the front glass surface of PV modules if the power output is to be optimised, and over 90% of modules are currently supplied with AR coatings. The overwhelming majority of commercial AR coatings are single layer porous SiO₂, deposited by sol–gel methods.
The author demonstrated great future of development of coating layer on PV panel where its great self-cleaning effect is enhanced by the mechanical sound absorption into the PV module and hydrophilic coating. The photocatalyst coating can increase the efficiency of solar cell by 2% and maximum power upto 4%.
More importantly, the coated glass was also used as a PV cover to simulate encapsulation and discuss the effect of coating application on PV cells. The results show that the coating prepared by a simple process has ultra-high transparency, excellent self-cleaning ability, and durability, and especially shows an increase in light transmission of .
