Description
Dispositif optique photovoltaïque à filtration dichroïque variable avec miroir dichroïque convexe local Introduction à l’art :Photovoltaic optical device with variable dichroic filtration with local convex dichroic mirror Introduction to art:
La fabrication de module photovoltaïque cristallin requiert le processus suivant : nettoyage du verre ou positionnement d’un matériau à forte transparence positionnement d’un film encapsulant EVA « Ethylène Vinyle Acétate » qui est en majorité de l’éthylène vinyle acétate sur le verre ou matériau à forte transparence soudure d’un ruban de cuivre ayant une couche de protection à base d’un alliage à base d’argent, de plomb et d’étain : la température de la soudure n’excède pas 250°C et ne dure pas plus de 3 secondes par cellules solaires ayant des zones en forme de ligne collecteur de courant des métallisations de l’émetteur sur une largeur de 1,5 à 3 millimètres interconnexion de la polarité négative ‘face avant d’une cellule d’un substrat de type P à la polarité positive ‘face arrière d’une cellule d’un substrat de type P‘ par exemple disposition en rangée de cellules soudées interconnexion des rangées pour un montage en série des cellules solaires nécessitant une soudure de chaque ligne de collecteur de courant positionnement d’un film encapsulant sur la matrice de cellules positionnement d’un film arrière de protection électrique ou d’un verre ou autre matériaux isolant lamination à des fins d’encapsulation des cellules solairesThe manufacture of crystalline photovoltaic modules requires the following process: cleaning of the glass or positioning of a material with high transparency positioning of an encapsulating film EVA "Ethylene Vinyl Acetate" which is mostly ethylene vinyl acetate on the glass or material high-transparency welding of a copper ribbon having a protective layer based on an alloy based on silver, lead and tin: the temperature of the weld does not exceed 250 ° C and does not last more than 3 seconds per solar cells having current collector-like areas of the emitter metallizations over a width of 1.5 to 3 millimeters interconnection of the negative polarity front face of a cell of a substrate of type P at the positive polarity 'rear face of a cell of a P type substrate' for example row layout of welded cells row interconnection for a mounting in s solar cells requiring soldering of each current collector line positioning of a film encapsulating on the matrix of cells positioning of an electric protective backing film or glass or other lamination insulating material for encapsulation purposes solar cells
Cette technique est unilatéralement utilisée mais a des inconvénients : le matériau encapsulant EVA a une viscosité d’une grande variabilité en fonction de la température ce qui induit une pression mécanique sur l’ensemble du dispositif des cellules solaires interconnectées le matériau encapsulant EVA contenant 1% d’eau libère de l’acide acétique et du peroxyde d’hydrogène en permanence qui se retrouvent piégés dans le module photovoltaïque entraînant des corrosions, des réactions chimiques avec les surfaces des cellules solaires, des réactions chimiques avec la surface intérieure du verre et crée la corrosion du verre par la formation de halogénures qui sont des pièges d’électrons mais aussi avec le polymère utilisé en protection électrique du module le matériau EVA ayant un indice de réfraction part réelle variant entre 1,49 et 1,47 sur la bande de rayonnement solaire, ce qui correspond une réponse spectrale proche du verre blanc utilisé, à savoir que le verre ait un traitement particulier le matériau EVA étant réticulé à la surface du verre, il est très difficile de séparer par quelques techniques que ce soient le film EVA du verre et le recyclage du verre comportant l’EVA rend les matériaux constituant le verre trop pollués et donc rendent le recyclage du module non fonctionnel l’encapsulation de 60 cellules solaires sur silicium monocristallin de wafer de format pseudo carré de 156mm de côté obtenu par la méthode de croissance Czochralski, « CZ » cellule à homojonction et émetteur homogène de 18,6% de rendement entraîne les pertes suivantes : à partir d’un ruban interconnectant en série les cellules de 2mm de largeur par 0,2mm d’épaisseur et interconnectant les rangées de cellules thermo-soudées par un ruban de 5 par 0,3mm, les pertes électriques sont de 2,5% les pertes optiques sont de 1% pour un verre avec une couche de silice poreuse d’indice de réfraction variant entre 1,23 et 1,33 pour un verre de transmittance sur le spectre solaire de 93% le module cristallin de ces 60 cellules solaires de 18,6% aura un rendement de 15,85% soit 2,75% et son comportement en température sera très affecté par l’encapsulationThis technique is used unilaterally but has drawbacks: the encapsulating material EVA has a viscosity of great variability as a function of the temperature which induces a mechanical pressure on the entire device of the interconnected solar cells the encapsulating material EVA containing 1% of water releases acetic acid and hydrogen peroxide permanently trapped in the photovoltaic module causing corrosions, chemical reactions with the surfaces of solar cells, chemical reactions with the inner surface of the glass and creates the corrosion of the glass by the formation of halides which are traps of electrons but also with the polymer used in electrical protection of the module the EVA material having a refractive index real part varying between 1.49 and 1.47 on the strip of solar radiation, which corresponds to a spectral response close to the white glass used, To know that the glass has a particular treatment the EVA material being crosslinked on the surface of the glass, it is very difficult to separate by some techniques that it is the EVA film of the glass and the recycling of the glass comprising the EVA makes the materials constituting the too polluted glass and therefore make the recycling of non-functional module the encapsulation of 60 solar cells on monocrystalline wafer silicon of square-shaped format of 156mm side obtained by Czochralski growth method, "CZ" homojunction cell and homogeneous transmitter of 18.6% yield results in the following losses: from a ribbon interconnecting in series cells 2mm wide by 0.2mm thick and interconnecting the rows of heat-sealed cells with a ribbon of 5 by 0, 3mm, the electrical losses are 2.5% the optical losses are 1% for a glass with a porous silica layer of refractive index varying between 1.23 and 1.33 for a glass of transmittance on the solar spectrum of 93% the crystalline modulus of these 60 solar cells of 18.6% will have a yield of 15,85% or 2,75% and its behavior in temperature will be very affected by encapsulation
la cellule solaire de 18,6% sur silicium CZ d’orientation «1-0-0» à émetteur homogène aura un coefficient de variation de sa puissance par rapport à la température d’un facteur négatif de 0,45%/°Kelvin et le module cristallin utilisant l’EVA entre autre aura un coefficient de variation de sa puissance d’un facteur négatif de 0,51%/°K la combinaison des matériaux verres à 93% de transmittance avec l’EVA et des cellules à émetteur homogène est compatible mais l’évolution technologique des cellules à homojonction vers des émetteurs sélectifs et des passivations arrières, la réponse spectrale des cellules évoluent grandement rendant la combinaison des matériaux d’un module impropre et non efficiente le module cristallin silicium se caractérise également par le comportement optique du silicium à savoir un fort coefficient d’absorption dans les ultra-violets « UV » et une quasi transparence aux infrarouges « IR » et le comportement en fonction de la température d’un module cristallin est intimement lié à la capacité de capter la bande solaire spectrale dont les longueurs d’onde de 250 à 1300nm représentant 80% du spectrethe 18.6% solar cell on homogeneous emitter "1-0-0" CZ silicon will have a coefficient of variation of its power relative to the temperature of a negative factor of 0.45% / ° Kelvin and the crystalline modulus using EVA among others will have a coefficient of variation of its power of a negative factor of 0.51% / ° K the combination of glass materials with 93% transmittance with EVA and transmitter cells Homogeneous is compatible but the technological evolution of homojunction cells to selective emitters and back passivations, the spectral response of cells evolve greatly making the combination of materials of a module unsuitable and inefficient the crystalline silicon module is also characterized by the optical behavior of silicon, namely a high absorption coefficient in ultraviolet "UV" and near-infrared transparency "IR" and the behavior as a function of e the temperature of a crystalline module is intimately related to the ability to capture the spectral solar band whose wavelengths from 250 to 1300nm representing 80% of the spectrum
La présente invention décrit un dispositif intégré optique permettant de filtrer le spectre lumineux par trois composants pour apporter à la jonction de cellule solaire les photons aux longueurs d’onde absorbées et transmettre les longueurs d’onde utiles à des applications sous le panneau photovoltaïque et réfléchir les longueurs d’onde qui ne sont pas utiles à la production photovoltaïque.The present invention discloses an optical integrated device for filtering the light spectrum by three components to provide the solar cell junction with photons at absorbed wavelengths and to transmit wavelengths useful for applications under the photovoltaic panel and to reflect wavelengths that are not useful for photovoltaic production.
