Front Sheet and Thin Film PV Applications

Front Sheet and Thin Film PV Applications

DuPont Teijin Films offers a wide range of engineered speciality films which are suitable for use in both rigid and flexible thin film photovoltaic modules, either as deposition substrates for the active layer or as the basis for high performance barrier layers. These films offer excellent dielectric strength and robust mechanical properties, and can be further enhanced via coatings, additives and process conditions to improve the environmental resistance and adhesion performance. Products from DuPont Teijin Films have found application in a wide range of thin film photovoltaic technologies including amorphous silicon, dye sensitised solar cells (DSSC), organic photovoltaics (OPV), perovskite-based systems and other emerging platforms. 

Tailored Properties for Barrier Deposition 

  • High light transmission levels
  • Enhanced weatherability options with respect to UV light and hydrolysis
  • Strong adhesion to other layers and encapsulants
  • Robust mechanical properties for ease of processing and installation
  • Off-line stabilised Melinex® ST™ polyester films offering excellent dimensional stability in high temperature processes
  • A range of tailored film surfaces suitable for addition of high barrier layers
  • Highly innovative Melinex® PCS film with a protective layer that can be removed at the point of use to reveal a clean, uncontaminated polyester film surface
