Definitions
- the present invention relates to a method for attaching a connection conductor to a photovoltaic solar cell.
- connection conductors to solar cells e.g. Silicon solar cells
- solar cells e.g. Silicon solar cells
- Attaching connection conductors to solar cells is basically known and used, for example, to electrically connect several solar cells together, in particular to connect in series.
- both the front side and the back side of the solar cell have silver-plated terminal contacts to which the connection conductors are attached by means of soft soldering. If an aluminum layer improving the efficiency of the solar cell is provided on the rear side of the solar cell, its efficiency-improving effect can be impaired by applying the terminal contact.
- the soldering process is carried out in a known method by heating the solar cell to soldering temperature by irradiation of light of a suitable wavelength, for example in the short-wave infrared range in silicon solar cells.
- a suitable wavelength for example in the short-wave infrared range in silicon solar cells.
- flux is used during soldering.
- the use of flux has the disadvantage that the flux can not be completely removed after the connection conductors have been attached to the solar cells.
- the residual flux residues can impair the efficiency not only of the individual solar cells, but also of a solar cell module comprising the solar cells overall, at least in the long term.
- connection of two electrical conductors by ultrasonic soldering is known.
- a direct soldering of a connection conductor by means of ultrasound to a connection contact of a solar cell is not only expensive, but the solar cell can also be damaged.
- the invention has for its object to provide a method for attaching a connection conductor to a photovoltaic solar cell, by which the quality of the solar cell or a solar cell module comprising this is at least not significantly impaired.
- the object is achieved by a method having the features of claim 1 and in particular by applying a solder, in particular soft solder, to the solar cell by means of ultrasound soldering and connecting the connecting conductor to the solar cell while supplying thermal energy through the solder applied to the solar cell becomes.
- a solder in particular soft solder
- the idea according to the invention thus generally consists of applying the solder to the solar cell on the one hand and the actual connection of the connecting conductor to the solar cell on the other hand in two separate steps, in other words one after the other.
- the application of the solder to the solar cell certainly represents that is, a preparatory step for the actual connection of the connection conductor to the solar cell.
- each solar cell can be soldered on its own, without this having to take into account a future position of the solar cell provided in the module relative to other solar cells.
- solder by means of ultrasonic soldering makes it possible to produce an optimum electrical contact between the solder and a metallization of the solar cell, even without the use of flux. In this way, it is ultimately possible to connect the connecting conductor completely flux-free with the solar cell. Consequently, no flux residues which could have a negative effect in a solar cell module comprising the solar cell result from the method according to the invention.
- solder is applied to the solar cell with the formation of strip-shaped solder paths.
- solder sheets or contact tracks can, in particular on the back of the solar cell, be used as a current collection conductor, so that no additional bus bars need to be provided.
- the solder is directly, i. without an additional metallic intermediate layer, applied to an aluminum layer provided on the rear side of the solar cell.
- an additional metallic intermediate layer applied to an aluminum layer provided on the rear side of the solar cell.
- the connecting conductor is in turn provided with a solder layer before being connected to the solder applied to the solar cell.
- the connection conductor is so to speakquaintlotet.
- the solder layer considerably facilitates the connection of the connection conductor to the solder applied to the solar cell and improves the quality of the connection both in electrical and in mechanical terms.
- the formation of the solder layer on the connecting conductor takes place without the use of flux. This contributes to the achievement of a completely flux-free solder joint between the connection conductor and the solar cell and thus to the maintenance of an optimum efficiency of the solar cell and of a solar cell module formed therefrom.
- the thermal energy for connecting the connection conductor to the solder applied to the solar cell is provided by a light source.
- a light source This is a so-called "lamp soldering process", which is characterized by a especially good economy distinguishes.
- the light source emits in a wavelength range which leads to a particularly rapid heating of the solar cell to soldering temperature. In the case of silicon solar cells, light in the short-wave infrared range is particularly suitable for this purpose.
- connection of connecting conductor and solar cell takes place in a continuous process.
- Such a process allows particularly economical electrical connection of a large number of solar cells and thus ultimately enables particularly cost-effective module production.
- the supply of thermal energy by means of a light source is particularly well suited.
- a further subject of the invention is also a solar cell with at least one connecting conductor for the electrical connection of the solar cells with e.g. a further solar cell, wherein the connecting conductor is attached by means of a flux-free solder joint to the solar cell.
- the flux freedom of the solder joint contributes to the achievement and maintenance of an optimum efficiency of a solar cell module comprising the solar cell.
- connection conductor is soldered directly, ie without an additional metallic intermediate layer, to an aluminum layer provided on the rear side of the solar cell.
- directly soldering the connecting conductor to the aluminum layer can be dispensed with an additional, for example, silver, connection contact, by which the efficiency of the solar cell would be impaired.
- the direct soldering of the connecting conductor to the aluminum layer thus contributes to maintain optimum efficiency of the solar cell taken by itself and thus ultimately also a solar cell module comprising the solar cell.
- FIG. 1 shows an arrangement of a plurality of solar cells connected in series in cross section.
- Fig. 2 is a plan view of a front side of a solar cell of
- FIG. 3 is a plan view of a back side of a solar cell of FIG. 1.
- Fig. 1 three solar cells 10 are shown, which are electrically connected in series by means of connecting conductors 12.
- the number of series-connected solar cells 10 is not limited to three, but ultimately depends on the size of the solar cell module, to which the solar cells 10 are to be summarized.
- the solar cells 10 are silicon solar cells which are formed in a known manner from a crystalline silicon material 14 and have on their front side a front-side metallization 16 and on their rear side a back-side metallization 18.
- each solar cell 10 comprises two current collection elements arranged parallel to one another. 20 and a plurality of finger portions 22, which extend transversely to the current collecting sections 20 and are each electrically connected to one of the current collecting sections 20.
- the backside metallization 18 of each solar cell 10 is formed by an aluminum layer 24 which covers the backside of the solar cell 10 substantially over the entire area (FIG. 3).
- connection conductors 12 for series connection of the solar cells 10.
- the pillowslei- ter 12 extend both over the entire length of the front and over the entire length of the back of a solar cell 10. In principle, however, it is also possible to make the connecting conductors 12 shorter, so that they the front or Cover the back of a solar cell 10 only partially.
- connection conductors 12 are aligned with the current collecting sections 20, more precisely they are applied thereto.
- the connecting conductors 12 are connected directly to the current collecting sections 20 as well as to the aluminum layer 24 by means of a soft solder 26, 28, ie neither an additional current collecting section 20 and connecting conductor 12, nor between aluminum layer 24 and connecting conductor 12 an additional metal layer.
- the connecting conductors 12 may be formed, for example, from a flat copper strip, which has already been provided with a solder layer prior to attachment to the solar cells 10, ie has been preloaded.
- connection conductors 12 to the solar cells 10 will be explained in more detail below.
- a soft solder 26, 28 is applied in the form of a strip-shaped solder path. In this case, both the illumination of the front side of the solar cells 10 and the heating of the rear side of the solar cells 10 are carried out with the exclusion of flux.
- first the front side and then the rear side of the solar cells 10 are soldered. However, it is also possible to solder first the back and then the front or even both sides at the same time.
- the front side solder 26 is directly applied to the current collecting sections 20 of the front side metallization 16 by means of an ultrasonic soldering process.
- an ultrasonic sonotrode is moved over the current collecting sections 20 at soldering temperature and with the supply of solder wire in a movement parallel to the front side of the solar cell 10.
- solder wire instead of supplying a solder wire, it is also possible to place solder preforms on the current collection sections 20 and to move the ultrasonic sonotrode at soldering temperature accordingly over them.
- oxide layers are deposited on the current collecting sections 20 and / or on the soldering wire or have formed a solder preform, broken, so that a cohesive connection of solder 26 and current collection section 20 is achieved with optimal electrical properties and in particular with a minimal contact resistance.
- solder 28 is applied in the form of strips directly onto the aluminum layer 24 of the backside metallization 18, i.
- metal layer between the aluminum layer 24 and the soft solder 26 is formed.
- the solar cells 10 are positioned in a predetermined position relative to each other and the connecting conductors 12 are arranged on or below the solar cells 10 that they both with the front side Lot 26 of a solar cell and with the back Lot 28 of an adjacent solar cell 10 in Standing in contact.
- the solar cells 10 and connecting conductors 12 thus arranged are heated to the soldering temperature in a continuous process for the material-liquid connection of the connecting conductors 12 to the front and back-side solder 26, 28.
