Description

  • The invention relates to a method for bonding a strip-shaped conductor to a solar cell, comprising the steps:
    • - applying an adhesive to the conductor and / or to the solar cell; and
    • - Merging of the conductor and the solar cell, so that the adhesive adheres the conductor and the solar cell together.
  • Such a method is known from WO 2006/128203 A1 known. According to the known solution of the conductor with a continuous coating z. B. coated from adhesive, which serves as corrosion protection and possibly for electrical contacting of the conductor and solar cell. In this case, significant amounts of electrical conductive adhesive are used.
  • The invention has for its object to make the method mentioned by efficient use of a targeted adhesive.
  • In order to achieve the object on which the invention is based, the invention provides a method for bonding a strip-shaped conductor to a solar cell, comprising the steps:
    • - applying an adhesive to the conductor and / or to the solar cell;
    • - merging the conductor and the solar cell so that the adhesive adheres the conductor and the solar cell together;
    wherein the adhesive is applied in discontinuous form.
  • In the context of this invention, the term conductor designates an electrical conductor which has freely movable charge carriers and is therefore suitable for transporting charged particles. The conductor may be a metal, a metal alloy or a metallization on the surface of a non-electrically conductive or electrically conductive material, and preferably contain silver, copper, molybdenum, titanium and / or aluminum. The conductor is preferably used for receiving and forwarding the charge carriers from the surface of the solar cell and for connecting adjacent solar cells in order to interconnect the solar cells to modules. The adhesive is inventively in discontinuous form, d. H. plotted with temporal and / or spatial interruptions. The adhesive can be applied, for example, at the same time with spatial interruptions on a screen in the manner of the screen printing process. Alternatively, it is also possible that the adhesive is applied several times in the same place with time interruptions. The targeted use of adhesive, the conductor and the solar cell can be partially bonded, for example, to achieve electrical contact, while the mechanical strength of the adhesive bond is achieved by other means.
  • Preferred developments are subject matter of the subclaims.
  • The conductor may have a circular cross-sectional shape or a cross-sectional shape deviating from the circular shape. In particular, the conductor may be formed as a flat conductor with a substantially rectangular cross-section, wherein the side of the cross-section with the greater extent is preferably arranged to the surface of the solar cell. The width of the conductor or the width of the side of the cross-section with the greater extent is preferably in the range of 0.5 to 10 mm, preferably in the range of 1 to 7 mm, particularly preferably in the range of 2 to 5 mm. A flat conductor or flat wire can contact the solar cell over the large-area side of the larger-diameter cross-section and can be arranged on the solar cell in a tilted manner.
  • The solar cell can be designed as a crystalline solar cell or as a thin-film solar cell. A photovoltaic thin film solar cell preferably comprises a substrate and a coating having one or more vapor deposited or sputtered layers. The substrate is preferably made of glass, metal, in particular sheet metal, plastic or the like. The coating includes, for example, amorphous or microcrystalline silicon, gallium arsenide (GaAs), cadmium telluride (CdTe) or the like. The thickness of the coating is preferably in the range of 5 to 20 microns, preferably about 10 microns. The adhesive is preferably applied to the coating. The conductor is typically adhered to the coated side of the thin film solar cell because soldering or welding the conductor due to heat input can cause significant damage to the coating. The bonding method according to the invention is thus outstandingly suitable for thin-film solar cells. Although the thin-film solar cell is less efficient, it is much less expensive than crystalline solar cells, so that the reduced use of adhesive in terms of production costs is particularly evident.
  • It may prove convenient if the adhesive is applied in spaced-apart, mutually contacting or at least partially overlapping sections. Thus, interactions of the adhesive, in particular of two or more different adhesives or different adhesive components, can be deliberately brought about or specifically prevented.
  • It may be advantageous to apply the adhesive in spots, in open / closed lines and / or in fields, preferably in stripes, rings, circles and / or polygons. When the adhesive is applied in spots, an adhesive applicator is preferably over the area to be coated with adhesive. If the adhesive is applied in points, in open / closed lines or fields, the adhesive application device is preferably guided during the application of adhesive with a predetermined movement over the surface to be treated with adhesive. Due to the different forms of adhesive sections, the intrinsic properties and strengths of the adhesive bond can be set specifically.
  • It may prove useful if the adhesive is applied in a regularly recurring form, arrangement and / or dosage. As a result, even over larger adhesive surfaces uniform adhesive properties and strengths can be achieved.
  • It may be practical if the adhesive is in points with a diameter in the range of 10 to 1000 microns, preferably in the range of 100 to 700 microns, preferably in the range of 320 to 500 microns and / or a thickness in the range of 10 to 500 microns , preferably in the range of 20 to 200 microns, preferably in the range of 30 to 100 microns is applied, wherein the distance of the adhesive points preferably in the range of 10% to 5000%, preferably in the range of 100% to 2000% of the diameter of the points , Such adhesive dots produce desirable adhesive properties and strengths and can be accomplished with screens or electronically and / or pneumatically controlled adhesive applicators. With these ratios of area to distance of the adhesive dots can be saved over 80% conductive adhesive against a full-surface bonding, while still desirable adhesive properties and strengths can be achieved.
  • In an advantageous embodiment of the invention, the adhesive, preferably non-contact, by means of an electronically controlled device, preferably by means of a piezo-jet dispenser, applied. The device preferably has a plurality of adhesive sources or nozzles, so that the adhesive can be applied simultaneously in different sections. With an electronically controlled device, the adhesive can be applied evenly over larger adhesive surfaces with optimized adhesive use.
  • It may prove advantageous if two or more different adhesives, preferably in regularly recurring form, arrangement and / or dosage, are applied, wherein preferably at least one adhesive is applied in discontinuous form and / or at least one adhesive after the merging of the conductor and the solar cell is introduced by a capillary effect into a gap between the conductor and the solar cell. Various adhesives can be used to achieve adhesive properties that can not be achieved with a single adhesive. Preferably, a functional adhesive that provides a desirable function is applied particularly sparingly in discontinuous form, while the mechanical strength of the adhesive bond is achieved by a much lower cost adhesive, which is targeted between the previously applied adhesive areas z. B is metered by means of a piezo-jet dispenser or Luftdruckdispensers or subsequently introduced by the capillary effect in the gap between the conductor and the solar cell. By an subsequently introduced into the gap adhesive, the gap can be filled and / or sealed to prevent the ingress of dirt or moisture. The targeted use of expensive functional adhesive, the manufacturing cost of the adhesive bond can be significantly reduced.
  • In another advantageous embodiment of the invention, a conductive adhesive and / or a structural adhesive is applied, wherein the conductive adhesive and the structural adhesive are preferably applied in spaced-apart areas, wherein a region of the structural adhesive preferably surrounds at least a portion of the conductive adhesive in its entirety. The term conductive adhesive refers to an adhesive with electrically conductive properties in the context of this invention. The term structural adhesive in the context of this invention refers to an adhesive which has a lower electrical conductivity than the conductive adhesive and which preferably acts as an insulator which prevents the flow of current between electrical conductors. As a conductive adhesive, for example, an offset with silver particles adhesive can be used, which has a high electrical and possibly thermal conductivity. This conductive adhesive has a pasty consistency and a certain stickiness. As structural adhesives epoxy adhesives, PU adhesives, methacrylate adhesives, etc. may be used which have a pasty consistency z. B. for the piezo jet metering or a thin consistency may have. The low-viscosity adhesive is particularly suitable for being introduced via a capillary effect into a gap between the conductor and the solar cell. The conductive adhesive is preferably applied before the structural adhesive. The structural adhesive is preferably applied in a planar manner between conductive adhesive dots so that the structural adhesive completely surrounds the conductive adhesive dots. It can be between at least one Leitklebstoffpunkt and the structural adhesive Annular gap may be formed so that the structural adhesive does not touch the Leitklebstoffpunkt. This can prevent the adhesives from mixing.
  • In yet another advantageous embodiment of the invention, a multi-component adhesive is applied as the adhesive, wherein the adhesive components are preferably applied in sections overlapping each other at least in sections or brought into connection when the conductor and the solar cell are brought together. For this purpose, the adhesive components can be applied in advance to the surfaces to be merged of the conductor and the solar cell.
  • The object of the invention is also achieved by an arrangement comprising a band-shaped conductor and a solar cell, which are adhesively bonded by an adhesive, wherein the conductor electrically contacts the solar cell in spatially-spaced sections. To remove the resulting during operation of the solar cell currents, a full-surface contact is not required.
  • It may be advantageous if the spatially spaced portions consist of conductive adhesive and / or are formed as material projections which protrude over a bonded surface of the conductor and / or a bonded surface of the solar cell. Preferably, the conductive adhesive, which accomplishes the electrical contacting, applied particularly sparingly, while the mechanical strength of the adhesive bond by other means, for example. A much less expensive structural adhesive is achieved. The targeted use of expensive conductive adhesive, the manufacturing cost of the arrangement can be significantly reduced. Alternatively, the spatially-spaced portions are formed as material projections which protrude beyond a bonded surface of the conductor and / or a bonded surface of the solar cell. The conductive adhesive can be cured immediately after application of the adhesive within a few seconds (<10 sec.) Z. B. by hot air or radiation, whereby solid, electrically conductive projections arise. The spaced-apart portions may be provided in a regularly recurring pattern of shape and / or arrangement. The material projections may, for example, be dome-shaped, cylindrical, conical or frustoconical, polyhedron-shaped, pyramidal or truncated pyramid-shaped and contact the conductor and / or the solar cell linear, strip-shaped, annular, circular, polygonal or the like. For example, the material projections are fixedly or integrally connected to the conductor and / or the solar cell or made in one piece with the conductor and / or the solar cell, so that the conductor and the solar cell are directly contacted by the material projections. For example. By embossing the conductor from one side, such material protrusions can be created on the other side of the conductor. Preferably, the gap between the opposite surfaces of the conductor and the solar cell is filled by a structural adhesive, so that the structural adhesive completely surrounds the material projections and adheres the conductor and the solar cell in the merging of the conductor and the solar cell. Since the structural adhesive shrinks during curing or crosslinking, the material projections come under mechanical tension with the opposite surfaces of the conductor and / or the solar cell in pressure contact and make a good electrical contact. Thus, with complete abandonment of the expensive conductive adhesive efficient electrical contacting can be accomplished by an adhesive connection.
  • The object of the invention is further achieved by the use of a piezo-jet dispenser for applying a conductive adhesive to a band-shaped conductor and / or to a solar cell in discontinuous form in order to electrically contact the conductor and the solar cell via the conductive adhesive. By a piezo-jet dispenser, the adhesive can be applied in regularly recurring form, arrangement and / or dosage, so that even over larger adhesive surfaces uniformly good adhesive properties and strengths can accomplish. Accordingly, in the same or in a second step, a non-electrically conductive structural adhesive to achieve the required mechanical strength in the vacancies between the electrical conductive adhesive with a piezo-jet dispenser, air pressure dosing, etc. are dosed. The adhesive can be applied according to all features of the method described above.
