Abstract | Foil comprises (a) a first outer layer made of a molding composition containing at least 35 wt.% polyamide and 1-65 wt.% light reflective filler, (c) a second outer layer made of a molding composition comprising at least 35 wt.% polyamide and 1-65 wt.% filler, respectively based on the total molding composition. The polyamide in the molding composition of the layer (a) and/or the layer (c) is a polyamide elastomer comprising polyether ester amide and polyether amide, where the molding composition of the layer (a) and/or the layer (c) comprise 1-25 wt.% polyamide elastomer. An independent claim is also included for a use of the foil as a back cover of a photovoltaic module, where the layer (a) is connected to a sealing layer, in which the solar cell is embedded; and #photovoltaic module comprising the foil as the back cover. |
