High-Reflection Black Series
White Outer / Black Inner
HD-CPC-HB
The black appearance where it is seen, the white surface where it helps the module stay cool.
The argument against all-black modules has always been thermal as much as electrical: a black rear face radiates less heat, the module runs hotter, and the temperature coefficient quietly takes back some of the yield.
HD-CPC-HB is the construction that splits the difference — black on the inner face for the uniform appearance through the front glass and the reflectivity that produces the CTM gain, white on the outer face where nobody sees it and thermal behaviour is decided.
Why this one
- Average CTM gain of +2.66%Higher reflectivity than conventional black backsheets.
- Clean architectural integrationDimensionally stable with no light leakage, so the elevation reads as a single surface.
- Exceptional durabilityNo bubbling or fading after PCT 48 h, DH 1500 h, UV and damp-heat UV testing.
- 303 µm ±10% construction10 µm air coating, 288 µm PET middle layer, 5 µm high-reflectivity inner coating.

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 rooftops and visible installations
- Distributed and portable applications

Questions about White Outer / Black Inner
How is this different from the double-sided black product?
Same 303 µm platform and the same +2.66% average CTM gain. This one is white on the outer face; HD-CPC-H2B is black on both.
Will the white outer face be visible from the front?
No. What the viewer sees through the front glass is the black inner face.
Is it rated for 1500 V systems?
The CPC platform it is built on is designed for module system voltages up to 1500 V.
