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 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 risk of hydrolysis –that means no water molecule penetration into the surface.

 

 

 

 

 

Proven durability in the laboratory and in-situ on life-sized modules:
