Polyolefin backsheets taking confident first steps

摘要

Next-gen backsheets: Polyolefin-based backsheet suppliers show why they think that their developments could help to reduce PV LCOE. They call for module manufacturers to make use of this technology and gain experience with polyolefin. This was one of the topics at this year's EU PVSEC. One could think that, with the growing trend towards glass-glass modules, any discussion on backsheet materials for glass-foil modules is becoming less relevant. It would appear, however, that the opposite is the case. In 10 years' time backsheets will still comprise almost 60% of the market, according to the experts and the 30 companies surveyed for the International Technology Roadmap for Photovoltaics (ITRPV) 2017. And because the industry is expanding, the market for modules utilizing backsheets will even increase, by approximately 70% compared to its current volume, to 363 GW.
