陶氏化学公司2010年第四季度在美国俄亥俄州芬德利开始规模化生产密封胶薄膜材料组件，这一生产线将会满足在多晶硅和薄膜太阳能电池板上对薄膜密封胶的需求。
该公司表示，这条商业规模的生产线，被称为光线，将在2010年第四季度开始在芬德利线生产，并把该生产线作为公司计划产品升级和增加产能方面的一部分，去满足全球对密封胶和不同种类密封胶的需求。
公司声称，新密封剂能提高光伏组件生产效率，降低转换损耗，以及给组件提供更大的稳定性和与EVA的传统的密封材料比能提高模块的电气性能，从而增强其可靠性和延长模块的使用寿命。
Dow Chemical is ramping production of a new polyolefin-based PV module encapsulant film at its manufacturing plant in Findlay, OH, where a state-of-the-art production line has been added to address the growing demand for specialty films for use in crystalline-silicon and thin-film solar panels.
The company said that commercial-scale manufacturing of the new UL-listed film, called Enlight, will begin on the Findlay line in the fourth quarter of 2010, as part of a phase-in plan to upgrade production and increase capacity across the globe to address increasing demand for this and other differentiated encapsulants.
Dow claims the new encapsulants can enhance efficiencies in PV module production and lead to lower conversion costs, as well as offer greater module stability and improved electrical performance compared to EVA-based traditional encapsulant, thus improving the reliability and extending the service life of modules.
“Customers have found the films reduce cycle times up to 30% and that the lamination temperature windows can be extended," said Brij Sinha, global business development leader for Dow’s specialty packaging and films business. "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.”
