摘要： A back sheet for a photovoltaic module having a long lifetime even under extreme weather conditions is described. Furthermore, the back sheet according to the present invention is inexpensive. A method for the production of back sheets for photovoltaic modules is further described. The back sheet according to the present invention comprises an outer layer (1) adapted to form the exterior side of the photovoltaic module and an inner layer (2) in direct contact with the outer layer (1). The outer layer (1) comprises an acrylic polyol resin cross-linked with an alkoxy melamine. The outer layer (1) may further comprise at least a UV filter and/or one or more light stabilizers. Moreover, the outer layer (1) may further comprise titanium dioxide (Ti02).

摘要： A method for the production of protective sheets, preferably for application as back sheets for photovoltaic modules, is disclosed. This method allows obtaining stable back sheets with long lifetime even under extreme weather conditions. Moreover, the method of the present invention is inexpensive and solvent free. The method of the present invention is based on the concept of pre-treating the surface of an internal layer of the back sheet by chemical etching followed by deposition, on at least one treated surface, of an aqueous dispersion of self cross linkable materials and by subsequent reticulation of said dispersion on the pre-treated surface. According to the present invention, protective sheets may be provided without the employment of fluoropolymers.
摘要翻译：公开了一种用于生产保护片的方法，优选用作光伏组件的背板。这种方法即使在极端天气条件下也能获得长寿命的稳定的背板。此外，本发明的方法是廉价且无溶剂的。本发明的方法是基于通过化学蚀刻预处理背板的内表面的概念，然后在至少一个经处理的表面上沉积自交联材料的水性分散体，以及通过所述分散体在预处理表面上的后续网状。根据本发明，可以提供保护片而不使用含氟聚合物。
