Solar Materials

Backsheet

Hanwha Advanced Materials’ Backsheet maintains the highest efficiency of solar modules with perfect electrical insulation and excellent durability.

Product Info.

  • Various Film Processing Technology
  • Differentiation of MaterialApplication of Materials with Long-term Reliability
  • Various Products Line UpHigh-functional Product Family

It is attached to the back of a solar cell module to prevent penetration of water, shock and UV rays, and protects the cell and module.

For long-term durability, film processing technology such as coating/lamination and coextrusion is applied by using fluoric film, weather-resistant PET, and weather-resistant polyolefin film.

Application

Backsheet 어플리케이션

Type

HBS-P Series (PET Type)
Feature
  • Excellent Solar Reflectance achieved through bright white film
  • Outstanding Stability shown in DHT, HAST
  • Superb bond strength to EVA sheet
Type
  • 1,000V (White/Black/Transparent)
  • 1,500V (White/Black/Transparent)
Structure
  • Hydrolysis Resistant PET (outer) / Hydrolysis Resistant PET / Polyolefin (inner)

    <White>

  • Hydrolysis Resistant PET (outer) / Hydrolysis Resistant PET / Polyolefin (inner)

    <Black>

  • Hydrolysis Resistant PET (outer) / Hydrolysis Resistant PET

    <Transparent>

Hydrolysis Resistance PET   The special-processed Hydrolysis Resistance PET has better weatherability compared to the general PET and protects the module from extreme weather conditions
