4 FAQs about How to paste cellophane on photovoltaic panels

What is photovoltaic silver paste?

Photovoltaic silver paste is mainly composed of high-purity silver powder, glass powder, and organic raw materials, produced by mixing, rolling pulp, and other processes. Positive silver paste is a formula-based product; the precise ingredients affect the subsequent links, which in turn affect the silver powder.

Why do photovoltaic panels use silver paste on the back side?

The silver paste on the back side mainly plays the role of adhesion, and is mostly used on the backlit side of P-type cells. Therefore, the silver paste on the front side of photovoltaic panels requires a higher level of production process and electrical conductivity.

Why do solar panels need silicone adhesives & sealants?

Silicone adhesives and sealants offer superior flexibility, allowing them to absorb and distribute these stresses. This flexibility prevents cracking and other damage that compromises the panel's performance and longevity. Solar panels are constructed from a variety of materials, including glass, metals, and polymers.

Why is photovoltaic silver paste a good conductive material?

High conductivity: because silver is a good conductive material, photovoltaic silver paste has excellent conductivity, which helps to reduce the resistance and thus improve the current collection efficiency of the battery.
