PV Backsheet Material for Photovoltaic Manufacturing
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.
Offered in partnership with one of the European solar industry’s leading backsheet technology developers, our PV backsheets are compatible with a wide range of module technologies and ideally suited to the needs of today’s solar manufacturers. They are designed to help solar module producers maximize their cell quality and reliability, while significantly lowering their manufacturing cost-per-watt.
Our Solar Backsheet Products Include:
- Fluropolymer-based backsheets for crystalline modules
- Fluoropolymer-free backsheets for crystalline modules
- Backsheets for thin-film modules
- Backsheets for flexible modules, organic PV
- Backsheets for bifacial cells
- Backsheets for floating modules, sea water applications

The Role of Backsheets in PV Manufacturing
The primary function of the PV backsheet material is to offer protection to the solar module’s various components throughout its lifetime. This in turn ensures loss-free energy generation for the solar panel. The solar backsheet should be able to resist active environmental elements such as moisture, temperature changes, chemical substances and physical damages for years on end. The active electrical elements found within the modules must also be insulated to ensure the safety of surroundings. The PV backsheet material is layered atop an encapsulant on the solar cell:
