The Dow Chemical Company (Dow) is introducing ENLIGHT™ Polyolefin Encapsulant Films, which can enhance efficiencies in photovoltaic (PV) module production and lead to lower conversion costs. The films also can provide greater module stability and improved electrical performance versus traditional encapsulants, such as EVA-based products, which improves the reliability and extends the service life of PV modules. The new encapsulant films are suitable for C-Si and thin-film modules.
The new encapsulant films are the latest solutions spurred by Dow's focus on delivering sustainable solutions to address some of the world's most critical challenges - including the need for clean energy.
"ENLIGHT Polyolefin Encapsulant Films provide a number of benefits that help lower the total system costs of producing and using modules," said Brij Sinha, global business development leader for Dow's Specialty Packaging & Films business. "Customers have found the films reduce cycle times up to 30 percent and that the lamination temperature windows can be extended. The physical properties virtually eliminate bubbles, which leads to fewer rejects. Damage to equipment and modules is also markedly reduced because the process does not produce acetic acid."
Modules made with ENLIGHT Polyolefin Encapsulant Films can retain efficiency levels after more than 10,000 hours of damp heat exposure, whereas Dow testing shows that modules made with EVA typically show a sharp drop off in efficiency levels after more than 2,000 hours in damp heat.
