Abstract

See full text

Provided are a multi-layered sheet, a backsheet for a photovoltaic cell, a method of preparing the same and a photovoltaic module. The multi-layered sheet in which a resin layer including a fluorine-based resin has excellent durability and weather resistance, and also exhibits strong interfacial adhesion to a substrate or polymer coating layer is provided. When a drying process is performed at a low temperature in preparation of the multi-layered sheet, production cost can be reduced, producibility can be increased, and degradation in the quality of a product caused by thermal deformation or thermal shock can be prevented. Such a multi-layered sheet may be effectively used as a backsheet for various photovoltaic cells.
