NOVELTY - The roof panel comprises an integrated photovoltaic module, and a substrate (1) and an outer panel (2) geographically connected to each other. The outer panel comprises a thermoplastic layer (3). A photovoltaic layer system (6) is embedded in the thermoplastic layer. The substrate contains polymer, is formed as a flexible film and a rigid disk, and has a thickness of 0.8-4 mm. The photovoltaic layer system comprises a photovoltaically active absorber layer disposed between a front electrode layer and a back electrode layer. The outer panel has a thickness of 1.4-5 mm.    USE - Used as a roof panel.    ADVANTAGE - The roof panel can be manufactured with lightweight and increased stability.    DETAILED DESCRIPTION - The roof panel comprises an integrated photovoltaic module, and a substrate (1) and an outer panel (2) geographically connected to each other. The outer panel comprises a thermoplastic layer (3). A photovoltaic layer system (6) is embedded in the thermoplastic layer. The substrate contains polymer, is formed as a flexible film and a rigid disk, and has a thickness of 0.8-4 mm. The photovoltaic layer system comprises a photovoltaically active absorber layer disposed between a front electrode layer and a back electrode layer. The outer panel has a thickness of 1.4-5 mm. The layer system is divided into sections, which are connected with each other in series and/or parallel manner via electrically conductive connecting elements and/or busbars. A surface of photovoltaic layer system is 50% area of the roof panel. The roof panel is bent with a portion having a curvature radius of 600-900 mm. The integrated photovoltaic module has specific power of 50-150 W/m2. The thermoplastic layer has a thickness of 1-3 mm. An INDEPENDENT CLAIM is included for a method for manufacturing a roof panel.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic cross-sectional view of a roof panel.
