It has on its surface a network of narrow electrodes, usually silver or aluminum, designed to drain the current to one or more main electrodes from one to a few millimeters in width, also in silver or aluminum.
- Each cell provides an illumination dependent current at an electrical voltage that depends on the nature of the semiconductor and is usually in the range of 0.45V to 0.65V for the crystalline silicon. Voltages of 6V to several tens of volts are usually required to operate electrical appliances, a module photovoltaic is generally constituted by a plurality of cells electrically connected in series. A module of 40 cells provides for example nearly 24 volts. Depending on the currents requested, several cells can also be placed in parallel. A generator can then be made by adding possibly accumulators, a voltage regulator, etc.
- the patent application WO2004 / 095586 proposes to assemble the photovoltaic cells between front and rear plates, for example made of glass and to seal said plates with a peripheral organic sealing joint.
- the peripheral organic sealing seal delimits, thus, a sealed interior volume, in which the photovoltaic cells are arranged side by side.
- the assembly is then compressed and the interior volume is brought to a pressure below atmospheric pressure.
- Such a photovoltaic module has a good long-term seal and it is simpler and less expensive to manufacture than previous photovoltaic modules using a solder paste based on tin, lead and zinc.
- this configuration of photovoltaic module requires depositing one or more antireflection layers on both sides of the front plate, so as to overcome the optical discontinuity existing between the front plate and the antireflection layer of each photovoltaic cell receiving the light of the outside the cell.
- such a module, sealed with a peripheral organic seal is not sufficiently resistant to shocks.

- a peripheral sealing seal 5, preferably organic, is disposed between the front plates 2 and rear 3, around the assembly formed by the plurality of photovoltaic cells 4. Said seal 5 delimits, thus, a volume 6, in which the photovoltaic cells 4 are arranged.
- the pressure in the internal volume 6 can advantageously be maintained at a pressure lower than the atmospheric pressure.
- the photovoltaic module comprises a polymer film 7 coming into contact with both the photovoltaic cells 4 and with the front plate 2.
- polymer film is meant a film comprising at least one or more polymers. More particularly, the polymer film 7 is disposed on the part of the internal face of the front plate, corresponding to the part delimited by the sealing joint 5, that is to say the part of the internal face 2a of the plate before 2 forming the sealed interior volume 6 with the sealing gasket 5 and the corresponding part of the internal face 3a of the rear plate 3.
- the sealing gasket 5 is in direct contact with the internal face 2a of the front plate 2 and with the inner face 3a of the rear plate 3.
- the respective thicknesses of the front 2 and rear 3 plates are generally between 3mm and 4mm for the front plate 2 and between 0.1mm to 4mm for the back plate 3.
- the thickness of the seal 5 depends on the thickness of the cells photovoltaic 4, but it is generally between 0.2mm and 1mm and more typically 0.7mm.
- the polymer film 7 preferably has a thickness of the order of 10 .mu.m if the electrical interconnection conductors are arranged on the rear faces 4b of the photovoltaic cells 4 and of the order of the thickness of said conductors, typically 200 .mu.m, if they are arranged on the front faces 4a and rear 4b of the cells 4.
- the polymer film 7 may consist of one or more thin layers comprising a polymer matrix.
- the polymer matrix is, for example, formed by at least one polyacrylic polymer or at least one polyurethane polymer and, advantageously, it does not comprise a solvent.
- the polymer matrix may be a mixture of polyacrylate polymers or copolymers containing at least 50% of an acrylic monomer of general formula CR 1 R 2 , in which the radical R 1 is hydrogen or a methyl group and the radical R 2 is hydrogen or a saturated hydrocarbon chain containing between 1 and 30 carbon atoms.
- the saturated hydrocarbon chain may be branched or unbranched.
- the polymer film 7 has, moreover, a refractive index between that of the front plate 2 and that of the antireflection layers of the photovoltaic cells 4.
- the structure and / or the composition of the polymer film 7 is advantageously chosen from so that the polymer film has an intermediate refractive index, to ensure optical continuity in the photovoltaic module 1, between the front plate 2 and the photovoltaic cells 4, thus limiting the optical losses.
- the polymer film 7 is advantageously at least partially crosslinked.
- the photovoltaic cells 4 may comprise a silicon nitride antireflection layer, having a refractive index of the order of 2.3, while a glass plate has a refractive index of the order of 1, 5.

- the polymer film 7 will advantageously have a refractive index of the order of 1.76.
- the refractive index of the polymers does not exceed the value of 1, 7 or 1, 8.
- the polymer film 7 may, for example, be formed by a polymer matrix having a refractive index of the order of 1.7 or 1.8, for example a polyacrylic or polyurethane polymer matrix.
- the refractive index of the polymer matrix can be adjusted so that the polymer film 7 has an intermediate refractive index value between that of the front plate 2 and that of the photovoltaic cells 4.
- the refractive index of the polymer film 7 can reach the value of 1.9, by dispersing, in the polymer matrix of the thin layer or at least one of the thin layers in the case of a multilayer polymer film, a predetermined quantity of nanoparticles of at least one metal oxide.
- Said metal oxide nanoparticles are, moreover, transparent to light and they advantageously have a diameter of less than or equal to 10 nm.
- the metal oxide is, for example, titanium oxide or zirconium oxide.
- the nanoparticles of titanium oxide are, more particularly, obtained from titanium oxide chelated in an organic compound, such as an alkoxy-organosilane, an alcohol, a polyethylene glycol derivative or a carboxylic acid, so as to pass the titanium from its +4 valence state to its +6 valence state (more stable state).
- a dispersant is optionally used to prevent agglomeration of said nanoparticles.
- the proportion of metal oxide nanoparticles in the polymer matrix is advantageously chosen so as to find a compromise between the desired refractive index, which varies linearly with the quantity of nanoparticles, and the attenuation of the transmission of the light in said polymer film, necessarily caused by the presence of said particles.
- the proportion of nanoparticles of titanium oxide in the polymer matrix may advantageously be between 10% and 50% by weight and preferably between 25% and 30% by weight.
- particles of at least one rare earth for example a metal of the lanthanide series
- a polymer film 7 may comprise both rare earth particles and metal oxide nanoparticles.
- the presence of such a polymer film 7 in a photovoltaic module 1 makes it possible to ensure optical continuity from the front plate 2 to the photovoltaic cells 4. It is therefore no longer necessary to deposit anti-reflection layers on the inner face 2a of the front plate 2.
- the polymer film 7 improves the impact resistance of the photovoltaic module 1.
- a front plate 2 glass breaks.
- the polymer film 7 then serves as a buffer, avoiding the propagation of large cracks fragmenting the glass front plate.
- the glass is then maintained by the polymer film 7.
- tests have shown that the presence of such a polymer film 7 does not cause additional degassing that could be detrimental to the tightness of the interior volume 6.
- a photovoltaic module 1 such as that shown in FIG. 1 also has the advantage of being easier and less expensive to manufacture than modules requiring the presence of anti-reflection layers.
- the polymer film 7 is, in fact, deposited on the portion of the inner face 2a of the front plate 2, before the assembly of the photovoltaic cells and the peripheral sealing joint.
- the polymer film 7, deposited on the front plate 2 is advantageously in a state enabling it to exhibit sufficient adhesive properties to temporarily hold, during assembly, the photovoltaic cells against the front plate 2.
- FIG. 2 illustrates, by way of example, a particular embodiment of the photovoltaic module 1 as represented in FIG. 1.
- a polymer film 7 is deposited on a portion of the internal face 2a of the front plate 2, at a temperature of the order of 40 ° C.
- Said polymer film 7 has, in addition, a dynamic viscosity, at 40 ° C., of between approximately 10 3 ⁇ l (Poiseuille), or 10 4 Po or P (Poise) and about 5.10 3 Pl, or 5.10 4 Po or P.
- Such a viscosity range makes it possible, in fact, to deposit the film 7 on a front plate 2, advantageously arranged in a vertical position, without the polymer does not flow along the inner face 2a of the front plate 2. Then, the dynamic viscosity of said film 7 reaches, after cooling to ambient temperature, that is to say at a temperature of the order of 20 0 C, a dynamic viscosity of between about 2.10 3 P 1 (about 2 ⁇ 10 4 Po) and about 1.10 4 Pl (ie 1.10 5 Po).
- This gives said film 7 adhesive properties making it possible, during assembly, to maintain the photovoltaic cells 4 against the front plate 2. More particularly, when the front plate 2 is in a vertical position, such a range of dynamic viscosity makes it possible to maintain the photovoltaic cells 4 against the front plate 2, for at least 10 minutes, without there being displacement of said photovoltaic cells 4.
- the deposition of the polymer film 7 is followed by the assembly of the photovoltaic module and in particular of the front plate 2 coated with the polymer film 7, the photovoltaic cells 4, the peripheral sealing gasket 5 and the plate 3.
- the different elements of the photovoltaic module are preferably assembled, according to the method described in the patent application WO2004 / 09586.
- the front 2 and rear 3 plates are placed in a vertical position, parallel to each other, the polymer film 7 being arranged facing the internal face 3 a of the rear plate 3.
- the photovoltaic cells 4 and the peripheral sealing joint 5 are arranged between the two plates 2 and 3.
- the cells 4 are, more particularly, arranged side by side, while the seal 5 is disposed at the periphery of said cells.
- the photovoltaic cells 4, the sealing gasket 5 and the rear plate 3 are then directed towards the front plate 2 (arrows F), until:
- the photovoltaic cells 4 come into contact with the polymer film 7
- the sealing gasket 5 comes into contact with the internal face 2a of the front plate 2
- the assembly is then compressed by applying a pressure between the two plates 2 and 3.
- the sealing joint 5 delimits, then, a sealed interior volume 6 inside which are arranged the photovoltaic cells 4.
- a depression is then , advantageously carried out inside said volume 6, preferably by suction, to ensure a contact pressure sufficient to allow the electrical conduction necessary for the proper operation of the module.
- the polymer film 7 deposited on the inner face 2a of the front plate may advantageously be a crosslinkable polymer film.
- crosslinkable polymer film is meant a polymer film capable of being crosslinked, that is to say a polymer film in a disordered state and able to pass into a more orderly state.
- the polymer film can be crosslinked so as to avoid degassing phenomena.
- the method of crosslinking a polymer depends on said polymer employed. However, a large number of polymers can be crosslinked by exposing them to ultraviolet radiation. Thus, the polymer film 7 may advantageously be exposed to said radiation, through the front plate 2 (arrows F 'in FIG. 2), once the photovoltaic module has been assembled.
- the exposure of the polymer film 7 to ultraviolet radiation may be performed during assembly.
- the photovoltaic cells 4 are put in contact with the polymer film 7, then the parts of the polymer film 7 not covered by the photovoltaic cells 4 are directly exposed to ultraviolet radiation.
- the polymer film 7, provided with photovoltaic cells 4 is directly exposed to ultraviolet radiation, on the side of the internal face 2a of the front plate 2 and no longer through said plate 2, so that only the parts of the polymer film 7 not covered by the photovoltaic cells 4 are crosslinked.
- the peripheral seal 5 and the backplate 3 are successively contacted with the inner face 2a of the front plate 2, before the assembly is compressed.
- Such an embodiment improves the maintenance of the photovoltaic cells 4 against the front plate 2.
- a subsequent crosslinking can, if necessary, be performed using ultraviolet radiation, through the front plate 2. This subsequent crosslinking can be carried out by voluntarily or it can progressively occur during the use of the photovoltaic module.
- the production of the polymer film 7 integrates perfectly with the method of producing the photovoltaic module such as that described in the patent application WO2004 / 09586, without generating additional manufacturing costs, replacing a subsequent delicate and expensive step of deposition of layers. anti-reflection.
- the photovoltaic module 1 may also include an additional polymer film 8 covering at least a portion of the inner face 3a of the rear plate 3.
- additional polymer film 8 deposited on said back plate 3 makes it possible, in fact, to improve the impact resistance of said module.
- the material or materials constituting said film 8 may be identical or different from the deposited material (s) to form the polymer film 7. It must, however, be crosslinked before assembly of the module.
- a first polymeric resin film and a film for forming the front plate are laminated on the front surfaces of the photovoltaic cells and a second polymer resin film and a film for forming the back plate are laminated on the respective rear surfaces of the photovoltaic cells. Then, the laminate is heated at 150 ° C for 30 minutes. The first and second polymer resin films then form the sealing material.
- Many other documents of the prior art have a similar teaching. By way of example, mention may be made of patent applications WO-A-2004-038462 and EP-A-1722619 in which the polymer material used as a sealing material is an ethylene / vinyl acetate copolymer, also known under the name EVA.
- the polymer film used in the photovoltaic module does not have the function of sealing between the front and rear plates.
- This function is, in fact, performed by a peripheral sealing gasket 5.
- This peripheral sealing gasket thus delimits a sealed interior volume 6 in which the photovoltaic cells 4 are arranged. Therefore, the photovoltaic cells 4 are not embedded in a particular material.
- the side walls of the photovoltaic cells 4 are free.
- the polymer film 7 maintains the photovoltaic cells 4 against the front plate, during the assembly of said cells and the seal between the front and rear plates. It also makes it possible to ensure optical continuity between the front plate 2 and the photovoltaic cells 4 and to obtain good impact resistance.
- the polymer film 7 is not a laminate.
