What are back-sheet materials for photovoltaic modules?

Back-sheet materials for photovoltaic modules serve several purposes such as providing electrical insulation, environmental protection and structural support. These functions are essential for modules to be safe for people working near them and for the structures to which they are attached.

Why should you choose a solar backsheet material?

The PV Backsheet material you choose for your solar panel will have a considerable impact on how it withstands the elements and performs over the course of its lifetime. A reliable backsheet should be able to provide protection from moisture, physical damage and UV rays, while also minimizing electrical discharge and thermal degradation.

Why do photovoltaic cells need a backsheet?

Water and dust particles can lead to corrosion and pitting, posing a threat to photovoltaic cells. The backsheet’s role is to shield against moisture-related damage, including corrosion of electrical connections, insulation degradation, and the risk of short circuits.

Why do we need a backsheet for PV modules?

In addition, the backsheet can allow acetic acid to pass through effectively to reduce internal corrosion, and the excellent optical properties of such backsheets can also improve the output of PV module. The future of the co-extrusion process for the production of backsheets requires a high degree of attention.
