NOVELTY - The photovoltaic module to generate power, comprises a light-receiving surface side-sealing resin layer (2), a photovoltaic cell (31), a back surface side-sealing resin layer (4) and a back surface-sealing weatherproof film (5), which are laminated sequentially to each other on a light-receiving glass (1) and are formed into an integral piece. A part or an entire of the back surface side-sealing resin layer consists of a two-layered structure consisting of the back surface side-sealing resin layer and a new sealing resin, which are laminated together.    USE - The photovoltaic module is useful to generate power, and useful in buildings, warehouses, gymnastic halls or large capacity public buildings.    ADVANTAGE - The photovoltaic module can be easily produced with less effort, weatherproofness, high durability, high reliability and less power consumption in faster manner thus utilizing the module in exposed outdoor locations over a long time.    DETAILED DESCRIPTION - The photovoltaic module to generate power, comprises a light-receiving surface side-sealing resin layer (2), a photovoltaic cell (31), a back surface side-sealing resin layer (4) and a back surface-sealing weatherproof film (5), which are laminated sequentially to each other on a light-receiving glass (1) and are formed into an integral piece. A part or an entire of the back surface side-sealing resin layer consists of a two-layered structure consisting of the back surface side-sealing resin layer and a new sealing resin, which are laminated together. The new sealing resin and a new back surface sealing weatherproof film are sequentially laminated. The laminated new sealing resin is cured for cross-linking. The new sealing resin to be laminated on a portion has a shorter cross-linking time and a lower cross-linking temperature than that of the existing sealing resin sealing the photovoltaic module, and contains a larger amount of an anti-ultraviolet agent than that of the existing sealing resin sealing the photovoltaic module. The new back surface-sealing weatherproof film to be laminated on the portion, in which the film is peeled, is black on the light-receiving surface side. An INDEPENDENT CLAIM is included for a regenerated photovoltaic module.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic cross-sectional view of a structure of a photovoltaic module.
