NOVELTY - A photovoltaic module (10) comprises photovoltaic element (12) including back protection layer made from polyester type film, reinforcing support sheet, and an adhesive material adhesively attached between the reinforcing support sheet and the protection layer. The adhesive material is adapted to be applied to the reinforcing support sheet during final installation at room temperature.    USE - For attachment to supporting structure on buildings, vehicles or other fixed or mobile structure for producing electrical current.    ADVANTAGE - Photovoltaic module device has useful life. Ensures the stability for the layers to maintain their fixed positions during its handling and installation.    DETAILED DESCRIPTION - Photovoltaic module comprises photovoltaic element including photovoltaic solar cells (14) each with one side arranged to receive sunrays for generating electrical current in response to sunlight impinging on the cells and another side facing the support structure. The solar cells are encapsulated between sealant, adhesive layers to form the photovoltaic element. The photovoltaic element includes back protection layer made from polyester type film, a reinforcing support sheet, and an adhesive material adhesively attached between the reinforcing support sheet and the protection layer. The adhesive material is adapted to be applied to the reinforcing support sheet during final installation at room temperature. An INDEPENDENT CLAIM is also included for a method for producing a photovoltaic element comprising stacking a cover face plate having an adhesive layer provided on one surface being applied to the side(s) of the solar cells facing sunlight, an insulating protection layer with adhesive material applied between the same and the other side of the solar cell(s); laminating the cover plate and the protection layer with the solar cells; and bonding the reinforcing sheet to the protection layer with adhesive material at room temperature.
