Structural Protection Layer
CPC/CDPC
HD-CPC-T / HD-CDPC-FT
Organic material in place of glass, over 90% transmittance, UV resistance above 500 kWh/m².
Remove the front glass from a module and you remove its skeleton. Something has to hold the laminate flat, spread point loads and keep the cells from flexing, and it has to do it while passing more than 90% of the light through.
HD-CPC-T and HD-CDPC-FT are that layer: a transparent fluorinated CPC sheet for the back and a 575 µm transparent front sheet for lightweight crystalline silicon modules, both weather-resistant, lightweight and priced for portable-scale production.
Why this one
- Organic material replaces glassWeather-resistant, lightweight, high transmittance and low cost — the published best choice for packaging portable components.
- UV resistance above 500 kWh/m²With damp-heat UV above 75 kWh/m².
- Over 90% light transmittanceWhich is what makes a transparent structural layer viable in front of the cells at all.
- Two constructionsHD-CPC-T at 315 µm total as an insulating backsheet, and HD-CDPC-FT at 575 µm as a transparent front sheet for lightweight modules.

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
- Portable and foldable modules
- Lightweight distributed modules
- Greenhouse and semi-transparent installations

Questions about CPC/CDPC
What is the difference between HD-CPC-T and HD-CDPC-FT?
HD-CPC-T is a 315 µm insulating backsheet — 10 µm air coating, 300 µm PET, 5 µm inner coating. HD-CDPC-FT is a 575 µm transparent front sheet with a UV cut-off air side and a 560 µm middle layer.
Can it be used on both faces of a module?
Yes, that is the point of the pair: the front sheet and the backsheet come from the same chemistry, so thermal behaviour during lamination matches.
How does the cost compare with glass?
It is published as a low-cost route relative to glass for portable components, with the weight saving as the larger commercial benefit.
