Super hydrophobic film for photovoltaic panels

Are superhydrophobic and superhydrophilic coatings suitable for solar PV panels?

Self-cleaning materials including super-hydrophobic and super-hydrophilic coatings have been applied for solar PV panels due to their surface wettability and surface micro-structure [11, 12, 13, 14]. Piliougine et al. prepared a super-hydrophobic coating to reduce dust deposition on photovoltaic systems.

Can a super-hydrophobic coating reduce dust deposition on photovoltaic systems?

Piliougine et al. prepared a super-hydrophobic coating to reduce dust deposition on photovoltaic systems. They found that the self-cleaning coating can significantly improve the performance of photovoltaic power generation reduction caused by dust deposition.

What is Super hydrophobicity of photovoltaic craters?

Depositing silica and polystyrene on the leaf network can result in volcanic craters with super-hydrophobicity. After testing, the obtained sample WCA can reach approximately 162°. There are many methods based on CVD, and they are widely used in the self-cleaning of photovoltaic panels.

Which materials are used to make super hydrophobic coatings?

Super-hydrophobic materials such as organosilicon compounds, fluorinated polymers, and some inorganic materials are popular. TiO 2 is widely used to prepare super-hydrophilic coatings on glass covers of photovoltaic panels due to its good photocatalytic activity.

Are solar panels antireflective and photocatalytic?

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.

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.
