DYMAT® FOR HETEROJUNCTION CELLS

GREEN BLACKSHEET

Coveme has developed a range of revolutionary backsheets specifically designed for photovoltaic modules with heterojunction cells. These products have an innovative integrated barrier layer that gives the backsheet a low WVTR and guarantees excellent protection for heterojunction cells which are particularly sensitive to moisture. Furthermore, these backsheets, not having an aluminum layer, facilitate the production process of assembling the module. They are available in white, transparent black and versions for installations up to 1500 VDC.

PRODUCT FEATURES:

  • Low WVTR
  • Integrated barrier layer
  • Enhanced UV protection
  • White, transparent and black version available
