Solutions for photovoltaic applications

Fulfilling the demands of a future energy supply

Worldwide efforts to increase the share of renewable energy will increase the demand for accordant technologies such as conventional solar panels or lightweight and versatile flexible solar panels. For the growth market for photovoltaic applications (PET films in the thickness range of presently approx. 250 µm), Brückner has focused on the development of adequate line concepts. The newly designed lines have responded to the specific demands for such films:

  • Profiling of the melt to ensure the required optical properties
  • Smooth and gentle film handling during orientation and winding to avoid mechanical surface faults and to ensure the required form stability for subsequent processing steps
  • Recycling systems allowing not only the recycling of edge trim fluff of finished film but also of the considerably thicker primary film after the casting roll
