6 FAQs about [Photovoltaic panel coating technology]

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.

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.

Do PV modules have anti-reflection coatings?

These reflection losses can be addressed by the use of anti-reflection (AR) coatings, and currently around 90% of commercial PV modules are supplied with an AR coating applied to the cover glass , . The widespread use of AR coatings is a relatively recent development.

Which method is suitable for self-cleaning coating of photovoltaic modules?

The preparation methods suitable for self-cleaning coating of photovoltaic modules include LBL, CVD, sol–gel method, and plasma-etching technology. LBL, CVD and sol–gel technologies are all CVD-based surface treatment technologies, which have difficulty in precision control. Sol–gel method and LBL are both economical.

Can a sol-gel coating improve optical performance for photovoltaic applications?

However, balancing mechanical durability, self-cleaning characteristics, and optical performance for photovoltaic applications remains challenging. This study focuses on synthesizing a composite coating through the sol-gel method, aiming to achieve high optical transmittance and superior mechanical properties.

Do solar modules need a coating?

The enormous scale of modern solar utilities, with some exceeding 500MWp, makes it undesirable and impractical to re-apply coatings to modules in the field. Over 90% of PV modules are now supplied with an AR coating.
