High-performance backsheets for PV modules

We offer two types of photovoltaic backsheet, depending on your needs: the all-purpose D series delivers great all-round performance, while the B series is suitable for niche high-end applications. No matter what type you choose, our backsheets are co-extruded, recyclable and made of a strong polyolefin core.

The DSM D series backsheet

This all-purpose backsheet delivers mainstream excellence, providing great performance and superior durability for a wide range of modules. This includes the most reliable moisture barrier and the best UV resistance and long-term mechanical performance in its class. 

  • Best performance/cost for all climates.
  • Outstanding UV resistance and mechanical properties. 
  • Excellent moisture barrier, suitable for a wide range of modules.

The DSM B series backsheet

Our B series offers extreme performance for harsh environments. It’s ideal for high-power class PV modules that need to perform long-term in extreme environments in extreme humidity, saltwater, high winds with debris, and rural ammonia - preventing early module failure and maintaining bankable uptime.

  • Top-class durability performance comparable to or even exceeding PVF backsheets.
  • With PA12 outer layer for extreme chemical and abrasion resistance.
  • Winner of the 2018 All Quality Matters (AQM) award from TÜV Rheinland
