High-Reflection Black Series
Double-Sided Black
HD-CPC-HB / HD-CPC-H2B
All-black appearance with an average CTM gain of +2.66% over conventional black backsheets.
All-black modules sell on rooftops and lose power doing it. A black backsheet absorbs the light that falls in the gaps between cells instead of reflecting it back, and that cost has been accepted as the price of appearance for a decade.
This series narrows the gap. Higher reflectivity than a conventional black backsheet returns an average CTM gain of +2.66%, with no bubbling or fading after PCT 48 h, DH 1500 h, UV and damp-heat UV testing.
Why this one
- Average CTM gain of +2.66%Against conventional black backsheets — most of the power an all-black module normally gives away.
- Aesthetically clean and structurally stableClean architectural integration with dimensionally stable performance and no light leakage.
- Exceptional durabilityNo bubbling or fading after PCT 48 h, DH 1500 h, UV and damp-heat UV accelerated ageing.
- Two constructionsHD-CPC-HB outer white with inner black, and HD-CPC-H2B black on both faces, at 303 µm ±10%.

Storage and shelf life
High storage stability with no special storage requirements. Warranty period is one year under cool, dry storage conditions; laminating process generality should be evaluated after that period.
Applications
- Utility-scale PERC monocrystalline glass-glass and glass-backsheet modules
- Residential and architectural installations
- Distributed and portable applications

Questions about Double-Sided Black
What is CTM gain?
Cell-to-module ratio — how much of the summed cell power survives into the finished module. +2.66% on average is what this construction returns against conventional black.
Double-sided black or white outer / black inner?
Double-sided black where the rear is visible, for example on a carport or a pergola. White outer / black inner where only the front is seen and the white outer face helps the module run cooler.
Does the black surface make the module run hotter?
Any black rear surface reduces radiative cooling. The white outer / black inner construction exists precisely to keep the appearance while limiting that effect.
