New backsheet ICOSOLAR® CPO 3G to be launched at Intersolar Europe


For the development of this revolutionary backsheet ISOVOLTAIC, market and technology leader for solar backsheets, and Borealis, a leading provider of innovative polyolefin solutions for the global energy industry, have joined forces. In leveraging their respective areas of expertise, the two companies have now developed new and revolutionary products for the photovoltaic industry.


ICOSOLAR® CPO 3G – the solution for high efficiency modules


ICOSOLAR® CPO 3G, white and black


The new ICOSOLAR® CPO 3G backsheet is manufactured by ISOVOLTAIC, based near Graz, Austria, using Borealis’ solar grades QuentysTM produced in Schwechat, Austria. These polypropylene (PP) grades form the core layer as well as the outer layers of the backsheet. The backsheet’s performance-enhancing benefits extend the lifetime of PV modules and ensure greater operational reliability due to:

–           Increased module output thanks to excellent reflectivity

–           Superior water vapour transmission rate (WVTR) and acetic acid permeability

–           Outstanding hydrolytic stability and insulation properties

Because there are no adhesive layers, the risk of inner-layer delamination is eliminated. Furthermore, co-extruded PP, as a single-step production technology, ensures the highest production quality and homogeneity, and reduces manufacturing complexity. This further increases its appeal as a replacement for conventional PET based backsheets.
