  • Publication number: 20150083222
    Abstract: Provided are a backsheet for a photovoltaic module, a method of manufacturing the same, and a photovoltaic module. As a resin layer including a fluoropolymer is formed by coating an aqueous dispersion composition including a crystalline fluoropolymer, a pigment, an aqueous dispersion binder and water on a substrate by an in-line coating process in a process of manufacturing the substrate, a process of manufacturing the backsheet may be simplified. In addition, since the process of manufacturing the backsheet does not use a toxic organic solvent, the process may be environmentally friendly and economical, and may enhance both productivity and product quality.

  • Publication number: 20150075619
    Abstract: Provided is a multilayered film having excellent reliability and adhesive strength under a heat/water resistance condition, and excellent weather resistance and durability by forming a primer layer including a fluoropolymer and an oxazoline group-containing polymer on a base and forming a resin layer including a fluoropolymer on the primer layer. In addition, the multilayered film uses a low boiling point solvent, and thus is manufactured at a low drying temperature and with a low cost, resulting in reducing production costs and preventing degradation of quality of a product from thermal deformation or thermal impact. Such a multilayered film may be effectively used in a backsheet for a photovoltaic module to provide a photovoltaic module capable of maintaining excellent durability even in long-term exposure to an external environment.

  • Publication number: 20140246085
    Abstract: Provided are an aqueous dispersion composition, a backsheet for a photovoltaic module, a method of preparing the same, and a photovoltaic module. Since the aqueous dispersion composition includes a fluorine-based polymer, a pigment and an aqueous dispersion binder, a backsheet for a photovoltaic module using the aqueous dispersion composition is prepared without a toxic organic solvent, and thus is environmentally friendly and economical. In addition, as the aqueous dispersion binder is used, a chalking phenomenon in which the pigment projected on a surface of the backsheet is easily detached may be prevented, thereby enhancing both productivity and quality.
