PV Cell, Photovoltaics, Solar

In existing technologies the most popular backsheet construction is a “sandwich” of Mylar® PET polyester film between two layers of DuPontTM Tedlar®.

This trilaminate is commonly referred to as T/P/T. Mylar® polyester film is the ideal candidate for the TPT laminate because of its properties:

  • Excellent electrical properties
  • Meets water vapour barrier requirements
  • Has tailored dimensional stability
  • Is easy to handle
  • Robust “cut-through” and tear resistance

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.
