PV Backsheet Material Solution 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 the occurrence of electrical discharge and thermal degradation.

Offered in partnership with one of the European solar industry’s leading backsheet technology developers, our PV backsheet solution is compatible with a wide range of module technologies and ideally suited to the needs of today’s solar manufacturers. It has been designed to help solar module producers maximize their cell quality and reliability, while significantly lower their manufacturing cost-per-watt.

Co-extruded Polypropylene Backsheet

Our co-extruded polypropylene (PP) backsheet offers significant advantages in comparison to conventional material solutions for PV backsheets at a highly competitive price point. The absence of adhesive layers eliminates the risk of de-lamination, while the co-extruded PP yields the highest possible production quality and homogeneity while also reducing manufacturing complexity. A worthy substitute for its conventional PET-based counterpart, our innovative backsheet solution extends the lifetime of PV modules and ensures greater operational reliability and performance by providing:

  • Increased module output thanks to excellent reflectivity.
  • Superior water vapour transmission and acetic acid permeability.
  • Outstanding hydrolytic stability and insulation.

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:
