Title:
MULTILAYER FILM AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/058609
Kind Code:
A1
Abstract:
The embodiments of the present invention provide a multilayer film, a backing sheet for a photovoltaic cell, a manufacturing method thereof, and a photovoltaic module. The embodiments of the present invention can provide a multilayer film wherein a primer layer and a fluorinated polymer coating layer are formed by coating, so a mutual diffusion effect between materials of the respective layers allows the fluorinated polymer coating layer, which is a surface layer, to have excellent durability and weather resistance, and simultaneously, to have superior interfacial adhesion with the primer layer and the base. In addition, it is possible to reduce manufacturing costs in a process for manufacturing the multilayer film, to improve productivity, and to prevent decrease in the quality of a product caused by thermal deformations or thermal shocks. The aforementioned multilayer film can be effectively used, for example, as a backing sheet for various photovoltaic modules.
