Embodiment Construction

[0021] figure 1 The assembly of a photovoltaic cell 1 and an organic seal 4 arranged side by side between a front sheet 2 and a back sheet 3 is shown. For assembly, plates 2 and 3 and photovoltaic cell 1 are kept parallel to each other. In order to protect the photovoltaic cell 1 during assembly, the cell may be pre-fixed on one of the plates, for example on the back plate 3 , prior to the assembly of the plates 2 and 3 , as the corresponding electrical interconnection conductors may be. For example, they can be pre-glued by means of solvent-free organic glues, for example by derivatives of the polyvinyl family. The glue can consist of the same material as the organic seal 4 , for example a polybutene derivative. An organic seal 4 may then be deposited on one of the plates 2 and 3 , for example on the front plate 2 , around the set of photovoltaic cells 1 . The front sheet 2 and the back sheet 3 are then sealed by means of an organic seal 4, which may be thermoplastic, for ...

Abstract

The invention relates to a photovoltaic module comprising front (2) and rear (3) plates. In addition, an organic sealing joint (4) is disposed between the plates and defines an inner sealed volume (5) which is maintained at a pressure lower than atmospheric pressure and which contains the photovoltaic cells (1). The aforementioned sealing joint (4) is an organic joint, e.g. thermoplastic or polybutylene. According to the inventive method, the vacuum pressure is produced by means of suction. The method can comprise inert gas scavenging, the establishment of the vacuum pressure and compression sealing (P1). Said method can also comprise: partial sealing of the module, such as to leave two openings in the sealing joint (4); inert gas scavenging of the inner volume by means of the two openings; the establishment of the vacuum pressure; and, subsequently, the blocking of said openings.

Description

field of invention [0001] The invention relates to a photovoltaic module comprising an assembly of photovoltaic cells arranged side by side between a front plate and a back plate, and a tight internal volume arranged between said plates and defined at a pressure lower than atmospheric pressure A seal, the photovoltaic cell is arranged in the closed internal volume. Background technique [0002] Traditionally, to manufacture photovoltaic modules, photovoltaic cells are covered with a network of electrodes and connected to each other by soldered metal strips. The assemblies thus formed are then placed between two polymer plates which themselves are held between two glass substrates. The assembly is then heated to about 120° C. to greatly soften the polymer in order to make it transparent and airtight and to ensure the mechanical consistency of the modules. However, hermeticity, in particular against the penetration of moisture, is generally not achieved over the long term. ...
