The invention relates to a lightweight photovoltaic module () comprising: a transparent first layer () forming the front face, photovoltaic cells (), an assembly () encapsulating the photovoltaic cells (), and a second layer (), the encapsulating assembly () and the photovoltaic cells () being arranged between the first () and the second () layer. The invention is characterised in that the first layer () comprises a polymer material and has a thickness (e) of less than 50 &#x3bc;m, in that the second layer () comprises at least one composite material of the prepreg type containing polymer resin and fibres and has a areal weight of less than 150 g/m, and in that the encapsulating assembly () has a maximum thickness (e) of less than 150 &#x3bc;m.

Lightweight and flexible photovoltaic module comprising a front layer consisting of a polymer and a rear layer consisting of a composite material

A photovoltaic module includes a transparent first layer forming the front side of the photovoltaic module; a plurality of photovoltaic cells placed side-by-side and electrically connected; a polymer encapsulating assembly able to encapsulate the plurality of photovoltaic cells between a lower portion and an upper portion; a second layer made of a composite material based on polymer resin and on fibres, the encapsulating assembly and the photovoltaic cells being located between the first and second layers, at least the first and second layers defining edges of the photovoltaic module, the plurality of photovoltaic cells being spaced apart by a non-zero distance Dfrom at least one edge of the photovoltaic module; the photovoltaic module further comprises a third layer made of a composite material based on polymer resin and on fibres, the layer being located below the plurality of photovoltaic cells and above the lower portion of the encapsulating assembly and forming at least one peripheral strip extending from the at least one edge toward the centre of the module, the width (L) of which is larger than or equal to the distance D.

Flexible and light photovoltaic module

A lightweight photovoltaic module including: a first transparent layer forming the front face; photovoltaic cells; an assembly encapsulating the photovoltaic cells; and a second layer forming the rear face and containing an inner surface and an outer surface. The encapsulating assembly and the photovoltaic cells are located between the first and second layers. The module is characterized in that: the first layer is made from glass and/or polymer material and has a thickness that is less than or equal to 1.1 mm; the inner surface is substantially planar; and the second layer includes raised portions projecting from the outer surface, the outer surface and raised portions together defining the visible rear outer surface of the photovoltaic module.
