DuPont Teijin Films, the world's leading manufacturer of PET polyester films, offers a range of films tailored to the photovoltaic market.
First generation backsheets are based on polyester film laminated between two layers of Fluoropolymer film. Mylar® A polyester film is an ideal candidate for such laminates and can be engineered to offer improved hydrolysis performance and properties:
Benefits, durability and strengths...
- Excellent electrical properties
- Meets water vapour barrier requirements
- Tailored dimensional stability
- Easy to handle
- Robust "cut-through" and tear resistance
- Can be engineered to exceed 3000hrs damp heat
Mylar® PET polyester films for this application area are available in a range of thicknesses from 50 microns (2 mil) up to 250 microns (10 mil), with other thicknesses possible by discussion.
In the future heat stabilised Melinex® PET polyester films will have an important role in tomorrow's flexible solar cells as their increased dimensional stability provides an ability to be processed at higher temperatures.
