Conductive backsheets

Boost power in back-contact modules with our Conductive backsheet

If you want to get the maximum performance from high-power back-contact solar modules, look no further than our Conductive backsheet. Not only does its unique design deliver an increased power output of up to 3% by reducing resistive losses, this backsheet also enables you to develop beautiful black modules with industry-leading power density - ideal for residential and commercial rooftop applications and building- and-vehicle-integrated PV.


The DSM Conductive backsheet solves a long-standing problem for the solar industry by bringing efficiency and cost-effectiveness to back-contact modules.

The bright minds at DSM solved the challenge by creating a super-efficient interconnection cell design featuring a unique patterning system (a pivotal part of the manufacturing process for conductive backsheets).

The result: a durable, scalable, ‘lossless’ Conductive backsheet that enables the highest power density and output available today, thus maximizing every square centimeter of space available on the front of the module.

Our Conductive backsheets are compatible with MWT and IBC cells – and are ready and available for mass commercial production.

Industry support for back contact technology

Today, high power back-contact modules are being manufactured worldwide with our Conductive backsheet technology.

In North America, our strategic alliance with leading module manufacturer Silfab Solar has recently yielded the high-power, 370W Silfab Elite module – a premium product that meets growing demand in the residential rooftop segment.

In Europe, the innovative module manufacturer Energyra is not only using the DSM Conductive backsheet in its products, but also developing and testing various exciting new module concepts. Meanwhile, our solution is now set to be used in combination with the groundbreaking ZEBRA IBC cell technology developed by ISC Konstanz.

We also work with research partners across the industry, including TNO, the Dutch knowledge institute, and one of the early developers of MWT technology.

Ultimately, this is a technology that benefits everyone in the solar value chain – which is why we’re dedicated to working with a growing number of industry partners to ensure back contact cell technology comes of age.

Supporting you in Conductive backsheets

We complement all this with outstanding customer service, including expert advice and technical support available wherever in the world you are.

Same sun. More power.™
