ICOSOLAR® Encapsulant - Backsheet combined with new encapsulating material

  • Backsheet and thermoplastic encapsulating material in one product
  • Obvious advantages compared to materials used previously
  • Cost saving in module manufacturing process 

Lebring, 8. August 2012 

In ICOSOLAR® Encapsulant, ISOVOLTAIC offers an innovative encapsulating material which is combined directly with the established ICOSOLAR® backsheets and completely replaces a layer of encapsulating material in the module. This globally unique combination demonstrates ISOVOLTAIC’s technology leadership yet again.

With ICOSOLAR® 4002 (ICOSOLAR® AAA3554 with encapsulating material), ICOSOLAR® 4006 (ICOSOLAR® APA 4004 with encapsulating material) and ICOSOLAR® APA 3G plus (ICOSOLAR® APA 3G with encapsulating material), ISOVOLTAIC enables its customers to carry out more efficient production of photovoltaic modules.

ICOSOLAR® Encapsulant is manufactured from a new material (TPO – thermoplastic polyolefin) and has obvious advantage compared to materials used previously. A layer of encapsulant material between the cell and the backsheet is replaced completely thus simplifying the manufacturing process of photovoltaic modules. Combined with the established ICOSOLAR® backsheets, the encapsulating layer exhibits excellent adhesion to all common encapsulating materials and does not form any acetic acid in the damp heat test. By comparison with EVA, encapsulant exhibits less water absorption and water vapour permeability as well as improved damp heat and UV stability.

Module producers can save costs by using the new ICOSOLAR® backsheets with encapsulant. Simplified storage without air-conditioning becomes possible in addition to the saving in the layup process due to the reduction in components. ICOSOLAR® backsheets with encapsulant can also be ordered cut-to-size thus creating less waste in downstream processing.

Once again ISOVOLTAIC is using its many years of experience and close cooperation with its customers to bring innovative products onto the market. Now ISOVOLTAIC is offering ICOSOLAR® Encapsulant in conjunction with its polyamide-based backsheets. It is possible, however, to combine it with all ICOSOLAR® backsheets.
