Composition d'encapsulation de cellules photovoltateues. et procédé d'encapsulation à l'aide de cette comdositiOn
La présente invention concerne une composition d'encapsulation de cellules photovoltalques, comprenant un copolymère d'éthylène et d'acétate de vinyle, un peroxyde organique, un agent antioxydant, un agent de stabilisation contre la dégradation par le rayonnement ultraviolet, et un agent de captation de radicaux libres.Composition for encapsulating photovoltaic cells. and method of encapsulation using this comdositiOn
The present invention relates to a composition for encapsulating photovoltaic cells, comprising a copolymer of ethylene and vinyl acetate, an organic peroxide, an antioxidant agent, a stabilizing agent against degradation by ultraviolet radiation, and a free radicals.
Elle s'étend en outre à un procédé d'encapsulation de cellules photovoltaiques à l'aide d'une telle composition. It further extends to a method of encapsulating photovoltaic cells using such a composition.
On a déjà effectué ltencapsulation de telles cellules à l'aide d'une composition de ce genre, dans laquelle le copolymère d'éthylène et d'acétate de vinyle était à 33% d'acétate de vinyle, et d'indice de fusion 43 g en 10 minutes. The encapsulation of such cells has already been carried out using a composition of this kind, in which the copolymer of ethylene and vinyl acetate was 33% vinyl acetate, and with a melt index of 43 g in 10 minutes.
Une telle composition possède une bonne transparence (8bu4% en moyenne entre 400 et 1100 nm). Cependant, l'adhérence de ce film sur le verre de face avant ne se maintient pas suffisamment au cours du temps, lorsque les modules comportant ces cellules sont placés dans un environnement sévère au point de vue des conditions de température et d'humidité, même si l'on munit la surface du verre d'une mince couche de silane destinée à favoriser cette adhérence. Such a composition has good transparency (8bu4% on average between 400 and 1100 nm). However, the adhesion of this film to the front face glass is not sufficiently maintained over time, when the modules comprising these cells are placed in a harsh environment from the point of view of temperature and humidity conditions, even if the surface of the glass is provided with a thin layer of silane intended to promote this adhesion.
Le but de l'invention est donc de procurer une composition d'encapsulation de cellules photovoltalques qui adhère énergiquement sur la surface du verre de face avant même si le module est soumis à des conditions sévères de température et d'humidité. The object of the invention is therefore to provide a composition for encapsulating photovoltaic cells which adheres vigorously to the surface of the front glass even if the module is subjected to severe conditions of temperature and humidity.
La composition selon l'invention est caractérisée par le fait que le copolymère d'éthylène et d'acétate de vinyle est réticulable par chauffage entre 1200 et 1500C en présence du peroxyde organique, et par le fait qui elle comporte en outre un primaire d'adhérence constitué par un silane greffable sur le copolymère à la température de décomposition du peroxyde. The composition according to the invention is characterized in that the copolymer of ethylene and vinyl acetate is crosslinkable by heating between 1200 and 1500C in the presence of organic peroxide, and by the fact that it further comprises a primer adhesion consisting of a graftable silane on the copolymer at the decomposition temperature of the peroxide.
Elle répond en outre de préférence à au moins l'une des énracté- ristiques suivantes
- Le copolymère d'éthylène et d'acétate de vinyle est à 28% d'acétate de vinyle.It also preferably meets at least one of the following characteristics:
- The copolymer of ethylene and vinyl acetate is 28% vinyl acetate.
- Le silane greffable est un silane méthacrylique ou vinylique. - The graftable silane is a methacrylic or vinyl silane.
- La proportion de silane méthacrylique ou vinylique est d'environ 1% en poids par rapport au copolymère. - The proportion of methacrylic or vinyl silane is approximately 1% by weight relative to the copolymer.
- Les quantités respectives de capteur de radicaux libres et d'absorbeur de rayonnement ultra-violet sont d'environ 0,4% et 0,9% en poids par rapport au copolymère. - The respective amounts of free radical scavenger and absorber of ultraviolet radiation are approximately 0.4% and 0.9% by weight relative to the copolymer.
L'invention s'étend en outre à un procédé d'encapsulation de cellules photovoltalques à l'aide d'une composition telle que définie ci-dessus, dans lequel on dispose les cellules dans le compartiment inférieur d'un appareil à deux compartiments séparés par une membrane souple, entre deux feuilles de la composition d'encapsulation, on met sous vide et on chauffe jusqu'à une température de 1200C sous vide, on introduit l'air dans le compartiment supérieur et poursuit le chauffage jusqu a ce que les feuilles de la composition fondent et enrobent les cellules, puis on sort celles-ci et on les laisse refroidir, caractérisé en ce que l'on poursuit le chauffage à une température entre 1200 et 1500C jusqu'à ce que le copolymère d'éthylène et d'acétate de vinyle ait subi une réticulation. The invention further extends to a method of encapsulating photovoltaic cells using a composition as defined above, in which the cells are placed in the lower compartment of an apparatus with two separate compartments by a flexible membrane, between two sheets of the encapsulation composition, it is placed under vacuum and heated to a temperature of 1200 ° C. under vacuum, the air is introduced into the upper compartment and the heating is continued until the sheets of the composition melt and coat the cells, then they are taken out and allowed to cool, characterized in that the heating is continued at a temperature between 1200 and 1500C until the ethylene copolymer and vinyl acetate has been cross-linked.
Il est décrit ci-après, à titre d'exemple et en référence à la figure unique du dessin annexé, deux compositions selon l'invention et un procédé d'encapsulation d'un module de cellules photovoltaiques à l'aide de telles compositions. It is described below, by way of example and with reference to the single figure of the appended drawing, two compositions according to the invention and a method of encapsulation of a photovoltaic cell module using such compositions.
Le copolymère d'éthylène et d'acétate de vinyle de la première composition est à 33% d'acétate de vinyle, et possède un indice de fusion de 43, mesuré selon la norme américaine ASTMD-1238 (Elvax 150 de du Pont de Nemours). On incorpore, pour 100 parties de copolymère, les additifs suivants - Peroxyde aliphatique 1,5 partie (2, 5-diméthyl-2, 5-di-t-butyl-peroxyhexane, nom commercial
Lupersol 101 ou Luperox 101) - Capteur de radicaux libres 0,1 partie (diamine secondaire, nom commercial ::
Tinuvin 770) - absorbeur de rayonnement ultra-violet 0,3 partie (hydroxybenzophénone, nom commercial
Cyasorb UV 531) - antioxydant 0,2 partie (triphénylphosphite substitué, nom commercial
Irganox 1076 ou Mark PRF1) - Silane méthacrylique 1 partie (nom commercial Z6030)
On peut également utiliser la composition - Copolymère d'éthylène et d'acétate de vinyle à 28% d'acétate de vinyle 100 parties ( ATO chimie 9006) - Peroxyde aliphatique Luperox 101 1,5 partie (2,5-diméthyl-2, 5-di-t-butyl-peroxyhexane) - capteur de radicaux libres 0,4 partie (diamine secondaire, nom commercial :
Tinuvin 770) - absorbeur de rayonnement ultra violet 0,9 partie (hydroxybenzophénone, nom commercial :Cyasorb W531) - antioxydant 0,2 partie (triphénylphosphite substitué, nom commercial
Mark PRF1) - Silane méthacrylique 1 partie ( désignation MEMO)
On observe que dans cette dernière composition les teneurs nécessaires de capteur de radicaux libres et d'absorbeur de rayonnement ultra-violet sont plus élevées que dans la précédente.The copolymer of ethylene and vinyl acetate of the first composition is 33% vinyl acetate, and has a melt index of 43, measured according to the American standard ASTMD-1238 (Elvax 150 de du Pont de Nemours ). The following additives are incorporated for 100 parts of copolymer - 1.5 part aliphatic peroxide (2,5-dimethyl-2,5, di-t-butyl-peroxyhexane, trade name
Lupersol 101 or Luperox 101) - 0.1 part free radical scavenger (secondary diamine, trade name:
Tinuvin 770) - 0.3 part ultraviolet radiation absorber (hydroxybenzophenone, trade name
Cyasorb UV 531) - antioxidant 0.2 part (substituted triphenylphosphite, trade name
Irganox 1076 or Mark PRF1) - 1-part methacrylic silane (trade name Z6030)
The composition can also be used - Copolymer of ethylene and vinyl acetate with 28% vinyl acetate 100 parts (ATO chemistry 9006) - Aliphatic peroxide Luperox 101 1.5 parts (2,5-dimethyl-2, 5-di-t-butyl-peroxyhexane) - 0.4 part free radical scavenger (secondary diamine, trade name:
Tinuvin 770) - ultraviolet absorber 0.9 part (hydroxybenzophenone, trade name: Cyasorb W531) - antioxidant 0.2 part (substituted triphenylphosphite, trade name
Mark PRF1) - 1 part methacrylic silane (MEMO designation)
It is observed that in this latter composition the necessary contents of free radical scavenger and of ultraviolet radiation absorber are higher than in the previous one.
Le module comprend les cellules photovoltarques 1 et leurs connexions placées sur une plaque avant en verre 2 entre deux feuilles 3, 4 de la composition de l'invention ; il est disposé dans le compartiment inférieur 5 de l'appareil à deux compartiments représentés dans la figure. The module comprises the photovoltaic cells 1 and their connections placed on a glass front plate 2 between two sheets 3, 4 of the composition of the invention; it is arranged in the lower compartment 5 of the device with two compartments shown in the figure.
La membrane souple 6 en caoutchouc silicone sépare le compartiment inférieur du compartiment supérieur 7. Elle est séparée de la feuille supérieure 3 par un film de protection 4A, par exemple en un polymère fluoré. On peut faire le vide simultanément ou séparément dans chacun des deux compartiments par les tuyauteries 8 et 9, munies des vannes 10 et 11. Une vanne 12 permet de remettre à la pression atmosphérique le compartiment supérieur. L'appareil peut être chauffé à l'aide de la plaque chauffante 13. The flexible silicone rubber membrane 6 separates the lower compartment from the upper compartment 7. It is separated from the upper sheet 3 by a protective film 4A, for example made of a fluoropolymer. A vacuum can be created simultaneously or separately in each of the two compartments by pipes 8 and 9, provided with valves 10 and 11. A valve 12 allows the upper compartment to be brought back to atmospheric pressure. The appliance can be heated using the heating plate 13.
Les opérations successives sont les suivantes 1/ Mise sous vide des deux compartiments et montée de la température ambiante à 1200C en 15 minutes. The successive operations are as follows 1 / Vacuuming the two compartments and raising the ambient temperature to 1200C in 15 minutes.
2/ Lorsque la température atteint 12O0C, on introduit l'air dans le compartiment supérieur 7. La pression atmosphérique vient donc s'appliquer par l'intermédiaire de la membrane 6, sur le module.2 / When the temperature reaches 120 ° C., air is introduced into the upper compartment 7. The atmospheric pressure is therefore applied via the membrane 6, on the module.
3/ On continue à élever la température jusqu'à 150 C en 15 minutes. 3 / We continue to raise the temperature to 150 C in 15 minutes.
Entre 1200 et 1500C, le copolymère fond, enrobe les cellules photovoltalques et réticule, du fait de la présence du peroxyde organique.Between 1200 and 1500C, the copolymer melts, coats the photovoltaic cells and cross-links, due to the presence of organic peroxide.
4/ On sort le module de l'appareil et on le laisse refroidir.4 / The module is removed from the device and allowed to cool.
Des essais d'adhérence initiale, puis après vieillissement accéléré à chaud et en milieu humide (950, 95g d'humidité), ont été effectués selon la norme ASTM D-903 en appliquant sur une plaque de verre des films d'une composition connue et de la deuxième composition décrite ci-dessus (à base de copolymère ATO 9006). Initial adhesion tests, then after accelerated aging in hot and humid conditions (950, 95g of moisture), were carried out according to standard ASTM D-903 by applying films of known composition to a glass plate and of the second composition described above (based on ATO 9006 copolymer).
La composition connue était la suivante - Copolymère d'éthylène et d'acétate de vinyle à 33% d'acétate de vinyle, d'indice de fusion 43 g/10 min. 100 parties ( Elvax 150 de du Pont de Nemours) - Peroxyde aliphatique Lupersol 101 1,5 partie - Capteur de radicaux libres Tinuvin 770 0,1 < partie - Absorbeur de rayonnement ultra-violet
Cyasorb UV531 0,25 partie -Anti-oxydant Mark PRF1 0,2 partie
Dans le cas de cette composition, la surface du verre était revêtue au préalable d'une couche de silane méthacrylique formant primaire d'adhérence.The known composition was as follows - Copolymer of ethylene and vinyl acetate at 33% vinyl acetate, with a melt index of 43 g / 10 min. 100 parts (Elvax 150 from du Pont de Nemours) - Lupersol 101 aliphatic peroxide 1.5 1.5 - Tinuvin 770 free radical scavenger 0.1 <part - Ultraviolet radiation absorber
Cyasorb UV531 0.25 part -Anti-oxidant Mark PRF1 0.2 part
In the case of this composition, the surface of the glass was previously coated with a layer of methacrylic silane forming an adhesion primer.
La force d'adhérence initiale de la composition connue était de 2,8 Kg/cm. Après un vieillissement de 630 heures à 950C et 95% dthumi- dité, la perte d'adhérence était totale. The initial adhesion strength of the known composition was 2.8 Kg / cm. After an aging of 630 hours at 950C and 95% humidity, the loss of adhesion was total.
La force d'adhérence initiale du film de la composition à base du copolymère ATO 9006 était très élevée, la rupture se produisant dans le film plastique. Après vieillissement de 630 heures à 956C et 95% d'humidité, la force d'adhérence résiduelle au décollement était de 2,94 Kg/cm. The initial adhesive strength of the film of the composition based on the ATO 9006 copolymer was very high, the rupture occurring in the plastic film.
