Document Type and Number:
WIPO Patent Application WO/2011/139052
Kind Code:
A2
Abstract:
The present invention relates to a multilayered sheet, to a backing sheet for a photovoltaic cell, to a method for preparing same, and to a photovoltaic module. The present invention relates to a multilayered sheet, comprising a resin layer containing fluorine resins that exhibits superior durability and weather resistance, as well as superior interfacial adhesion to a base or to a polymer coating layer. In addition, according to the present invention, a drying process for preparing the multilayered sheet can be conducted at a low temperature, to thereby reduce preparation costs, improve productivity, and prevent deterioration in product quality caused by thermal deformation, thermal shocks, or the like. The above-described multilayered sheet of the present invention can be effectively used, for example, as a backing sheet for a variety of photovoltaic cells.
