DuPont and Oerlikon Launch New Photovoltaic Encapsulant
(Nanowerk News) In the drive for more cost-effective solar energy, DuPont and Oerlikon Solar have collaborated on a new, ultra-thin white reflective solar photovoltaic encapsulant sheet that is part of the DuPont™ PV5200 Series. The new DuPont™ PV5223 white reflective polyvinyl butyral (PVB) encapsulant enables easier manufacturing of next-generation thin film photovoltaic modules that not only capture sunlight coming in, but also reflect more sunlight back through the module -- delivering more power.
At 0.45-mm thickness, new DuPont™ PV5223 white PVB encapsulant sheet is more than 40% lighter-weight than traditional 0.76-mm clear PVB and helps deliver more solar power at a lower cost per watt.
Encapsulants are among the most important materials to solar module manufacturers for high-volume module sealing and integration. Choosing or creating the right material not only speeds module production, but can significantly improve long-term power output and module durability.
"In the rapidly evolving and growing solar power market, equipment and materials leaders often innovate faster and more effectively by increasing collaboration,” said Steve Cluff, global business director – DuPont Photovoltaic Encapsulants. “DuPont’s market-driven science is supporting the solar industry's race for lower cost per watt. DuPont values the partnership with Oerlikon Solar, as we both view encapsulant technology playing an increasingly multi-functional role in next-generation photovoltaic modules."
"The PV5200 Series enables more power from our modules, lower material use, a smaller environmental footprint and easier lamination. It all adds up to a bright outlook for our module manufacturing customers," said Ivan Sinicco, senior manager, Module Development – Oerlikon Solar.
