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. | |
