NOVELTY - The module (100) comprises a rear reinforcement plate (101) including a laminated composite consisting of a superimposed rear pane, a photovoltaic layer system and a front pane, where thickness of the front and the rear panes is 1-2 mm. The rear reinforcement plate is arranged on the rear side of the rear pane, and comprises a structured metal sheet (5). A channel running in a straight line between an upper edge and a lower edge of the reinforcement plate is introduced into the metal sheet. The channel comprises an opening at the upper edge and at the lower edge.    USE - Photovoltaic module.    ADVANTAGE - The photovoltaic module can be manufactured with less weight and sufficient stability in an economical manner.    DETAILED DESCRIPTION - The module (100) comprises a rear reinforcement plate (101) including a laminated composite consisting of a superimposed rear pane, a photovoltaic layer system and a front pane, where a thickness of the front and the rear panes is 1-2 mm. The rear reinforcement plate is arranged on the rear side of the rear pane, and comprises a structured metal sheet (5). A channel running in a straight line between an upper edge and a lower edge of the reinforcement plate is introduced into the metal sheet. The channel comprises an opening at the upper edge and at the lower edge. Two contact faces are separated from one another by the channel and via which the reinforcement plate is connected to the rear side, formed on a surface of the rear reinforcement plate. The channel has a depth of 10-15 mm and a width of 5-20 mm. A thickness of the metal sheet is 0.3-0.4 mm. The rear reinforcement plate comprises reinforcement elements (9) in the form of struts between the adjacent channels. The rear pane is connected to the reinforcement plate via a polyurethane adhesive. A fixing element is arranged on a surface of the reinforcement plate. The front and the rear pane comprise a non-toughened, semi-tempered or toughened glass. The photovoltaic layer system comprises a photovoltaic active absorber layer between a front electrode layer and a back electrode layer. The photovoltaic layer system is contacted with a connection cable (16) electrically via a socket. An INDEPENDENT CLAIM is included for a method for producing a photovoltaic module.
