anti-reflective coating TT

  • Performance increase for PV-modules + 3 % (one-sided, AM 1.5, 300 nm to 1200 nm)
  • Performance increase for Solar-Thermal applications + 5 % (two-sided, AM 1.5, 300 nm to 2500 nm)
  • Improved incident angle modifier (IAM) > improved yield!
  • Closed pure silica dioxide surface for excellent mechanical properties
  • Excellent proven durability
  • Uniform optical appearance
  • Different surface structure with AR-coating:

Durabilityclsdprsm1

Long-term performance through unique closed porenanostructure.

The advantage of the closed and smooth surface is the sharply reduced sensitivity e.g. for fingerprints and a better clenability.
