The main subject matter of the invention is a photovoltaic module (1) comprising a transparent first layer (3) forming the front face of the photovoltaic module (1), a set (4) of a plurality of photovoltaic cells (5), and an assembly (6a, 6b) encapsulating the photovoltaic cells (5). The photovoltaic module (1) is characterised in that the first layer (3) comprises a plurality of plates (8) independent from each other, each plate (8) being located opposite a photovoltaic cell (5), in that the rigidity of the encapsulating assembly (6a, 6b) is defined by a Young's modulus (E) of the encapsulation material greater than or equal to 75 MPa at ambient temperature and a thickness (e) of the encapsulating assembly (6a, 6b) of between 0.4 and 1 mm, and in that the first layer (3) consists of at least one transparent polymer material belonging to the acrylic block copolymers or of a composition comprising at least one acrylic block copolymer having the following general formula (A) nB, in which: n is an integer greater than or equal to 1; A is an acrylic or methacrylic homo- or copolymer having a glass transition temperature greater than 50°C; and B is an acrylic or methacrylic homo- or copolymer having a glass transition temperature less than 20°C. |
