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
