    Abstract: The present invention relates to the use of a specific multilayer structure in the front and/or rear protective sheet of a photovoltaic module comprising photovoltaic cells covered with an encapsulant. This multilayer structure comprises a substrate enclosing at least one halogenated polymer and at least one stack of one layer (A) of SiO2 and one layer (B) of an SiOxNyHz material disposed between the substrate and the layer (A), said layers having given thicknesses. This stack is disposed on the face of the substrate turned towards the encapsulant and optionally on the opposing face of the substrate. It also relates to a photovoltaic module comprising the abovementioned multilayer structure in the front and/or rear protective sheet thereof.

    Abstract: The invention relates to biosourced vinylidene difluoride. The invention also relates to methods for preparation of biosourced vinylidene difluoride from various renewable raw materials. The invention also relates to homopolymers of vinylidene difluoride obtained from polymerization of said monomer, and also copolymers obtained by copolymerization of said monomer with one or several compatible comonomers. Finally, the invention relates to the use of said homopolymers or copolymers in applications, such as chemical engineering or electronics, in particular mass-market electronic devices.
