DNF provides diverse colors coated glass for BIPV Module cover glass. DNF BIPV Solar Color Glass not only produces eco-friendly renewable energy but also improves urban appearance to increase the added value of buildings.

  • Excellent Durability and Thermo-stability using a special inorganic material
  • High Transmittance & Color Realization by Spray Coating process
Advantages

High Transmittance & Non visible Solar Cell

  • Non-visible of internal solar cell with high efficiency (Max 97% compared to bare)
  • Harmonious Design with buildings and invisible solar cells

* With a high transmittance, the coating layer shows clear on the white back sheet
* Vivid Color Realization with a small amount of coatings on the black back sheet

Aesthetic improvement
  • Offering various colors based on 6 Main Colors(Gray, Blue, Green, Violet, Red, Gold)
  • Sparkle or Matt type available
  • Available for customizing colors & size as building exterior materials

Spray Coating Process
  • Spray coating on back side of cover glass. Applicable to various glass substrates
    - Low Fe float Glass / Patterned Glass / Anti-Glare Glass, etc.
  • Higher productivity & Durability than Dry Coating process
Method CVD Color Coating Dot parttern printing Wet Spray Coating
