Pushing POE for longer module lifetimes

Polyolefin-based films are estimated to represent around 20% of the market for PV module encapsulation materials – a share that has been growing each year since 2017. The challenge of potential-induced degradation in bifacial modules has thus far driven this shift, but polyolefin has plenty more to offer in ensuring long-term performance for PV modules. pv magazine recently caught up with Yuyan Li, technical leader for PV applications at Dow Packaging & Specialty Plastics – the supplier of Engage PV POE resin – to discuss the latest developments in the PV encapsulants market.
