WILMINGTON, Del., September 4, 2007 - DuPont Photovoltaic Solutions (DPVS) exhibits a broad and growing portfolio of films, resins for encapsulants, encapsulant films, conductive pastes and more, at the 22nd European Photovoltaic Solar Energy Conference and Exhibition (Hall 20, Booth 3) – the world’s largest PV event in Milan, Italy, September 3-7, 2007. DPVS is highlighting its latest technologies for both crystalline and thin film solar module systems, designed to increase the lifetime of solar modules, and improve productivity of PV module makers. DuPont is also emphasizing significant capacity expansion programs, in line with expected growth in the PV industry.

Additions to the DPVS portfolio include DuPont™ Bynel® resins and DuPont™ Surlyn® ionomer resins, both solventless adhesive solutions to ensure adequate bonding for non crystaline silicon technologies, and DuPont™ Kapton® polyimide film for flexible substrates that provide excellent electrical and thermal properties to thin film modules.

Significant enhancements to existing products within the DPVS portfolio include:

Key examples of successful recent applications of DuPont materials include the Building Research Establishment Innovation Park in London, England, and Living Tomorrow, The House of the Future, located near Brussels, Belgium. Both projects are sponsored by DuPont and intended to promote a greater understanding of PV power.

"High performing materials are at the essence of more efficient and longer lasting PV modules that are easier to install – these qualities are key to meeting customer needs, and DuPont has been putting science to work to help its PV customers succeed for over 20 years," Stacy Dedinas, global business manager, DuPont Photovoltaic Solutions, said. "We’re pleased to be expanding our portfolio of materials this year to include more exceptional offerings, like Surlyn®, Bynel® and Kapton®, and introducing significant improvements to established brands, with Tedlar® PV2100 series films and the new Solamet® screen printable thick film series, among others. At the same time, we’re making important capacity expansions that are critical to supporting the phenomenal growth in this industry."

DuPont and the solar industry estimate that the global PV market is growing at more than 30 percent per year. Within the European Union, the European Photovoltaic Industry Association (EPIA) estimates that by 2010, under favorable policy conditions, three giga watts (GW) of power could be installed annually, which is more than triple that in 2006. To meet the needs of the fast-growing photovoltaic solar energy market, DuPont last year announced that it has invested $50 million to expand production of DuPont™ Tedlar® polyvinyl fluoride film (PVF) at its Fayetteville, N.C., facility, which is on track to begin resin production in late 2007. Finished films are expected to be available in the first quarter of 2008. Coupled with additional expansions for other DuPont photovoltaic materials, DuPont's total planned investment is more than $100 million.
