DuPont Photovoltaic Solutions (DPVS) unveiled new DuPont™ PV5200 Series photovoltaic (PV) encapsulant sheets, based on polyvinyl butyral (PVB) polymer technology. As per the company, the new PVB photovoltaic encapsulant sheets offer physical and processing performance levels proven in laminated glass manufacturing, with additional features designed to meet the needs of thin-film solar power generation. Besides the PV5200 Series, DuPont anticipates the launch of several other PV sheet technologies in 2009.
The new series of PVB encapsulants are the first in a series of products emerging from recent DuPont development efforts to optimize encapsulants for faster, more efficient module production and longer service life. New DuPont™ PV5200 Series encapsulant sheets are said to offer excellent glass adhesion and proven safety glass performance, with high visible light transmission. Steve Cluff, business director, DuPont Photovoltaic Encapsulants said, "Unlike single-product suppliers, DuPont has an industry-leading range of clear, tough, adhesive materials that can be used in solar module manufacturing, including technologies adapted from related industries such as food packaging, roofing and building panel lamination."
