The role of silicone resin in photovoltaic panels

These materials are used to bond and seal various components of the panels, including solar cells, frames, junction boxes, and protective coverings.

The transparency of the glass slides was significantly improved after being coated with the HMDS@SNP anti-reflective solution. The epoxy-modified silicone resin/fumed silica (EMSR@HS) superhydrophobic solution was then dip-coated onto the AR-coated glass and fully fixed. Thus, highly transparent and durable self-cleaning coatings were obtained.

Generally, the encapsulate is a polymeric film which plays a critical role in avoiding environmental degradation or improving the stability of PV cells through the formation of a cross-linking network structure during the lamination of the PV module.

As shown by the results, when the methyl-silicone-coated glass is used, more light passes through the glass compared to when normal commercial PV glass with only a silica coating is used; this substantially improves the performance of the mini solar panel.

Whereas, in standard photovoltaic modules, silicones are limited to bonding and potting ap-plications, their properties make them suitable for a wider range of applications in customized solar panels (e.g. building integrated photovol-taics), where they play an essential role in the generation of energy.

6 FAQs about [The role of silicone resin in photovoltaic panels]

Can silicone be used for solar panels?

Silicones can also be used for the assembly of solar collectors, e.g. for bonding the front glass to the frame structure. WACKER silicone rubber grades are ideal for bonding the PV laminate, usually comprising a front glass, encapsulation films in front of and behind the solar cells, and a back-sheet, to the aluminum frame.

Why do PV panels need a resin coating?

The addition of the resin allows the various nanoparticles to cross-link and bond together, allowing the coating to remain durable in a variety of harsh environments. This functional coating allows PV panels to be self-cleaning while optimizing performance.

Can silicone encapsulants be used for photovoltaic modules?

These properties make them ideal candidates as encapsulants for photovoltaic modules. Internal evaluations at Dow Corning and with select external partners have shown that very efficient solar cells using silicones as the encapsulant can be assembled and show very good reliability.

Does methyl MQ silicone resin improve the performance of PV panels?

Wu et al. used methyl MQ silicone resin to modify the surface of SiO 2 nanoparticles (SNP) and obtained ultra-transparent self-cleaning coated glass, which has an average transmittance of over 95 % and maintains a certain self-cleaning ability, but there is no in-depth research on the performance of PV panels covered with coated glass.

How long do PV panels last with silicone gel technology?

Poulek, V.; Strebkov, D.S.; Persic, I.S.; Libra, M. Towards 50years lifetime of PV panels laminated with silicone gel technology. Solar Energy 2012, 86, 3103–3108. [Google Scholar] [CrossRef]

What type of rubber is best for solar panels?

WACKER silicone rubber grades are ideal for bonding the PV laminate, usually comprising a front glass, encapsulation films in front of and behind the solar cells, and a back-sheet, to the aluminum frame. Silicones are also a reliable solution to fix system components, such as junction boxes.
