Definitions
- the invention relates to a solar module for electrical
- the at least one arranged on a support body solar cell with each positive and negati ⁇ ven solar cell contacts, which are electrically interconnected via formed on the support body contact tracks, comprises.
- the electrically MITEI ⁇ Nander on an insulating support body in series, Pa ⁇ rallel- or series-parallel circuit connected solar cells of a solar module typically each have a back contact on the back and a front contact on the front side, which are formed as metallized surface area.
- a solar module described in DE 102 61 876 A1 provides for the formation of a directly applied Leitkle ⁇ bridge between the front contact of the solar cell and the associated contact trace on the support body, wherein the conductive adhesive bridge rests on an applied between the front and the back contact of the solar cell insulation layer , In addition to the lavish Ferti ⁇ supply the space requirement of trained with Leitkleber Georgian solar modules is relatively large.
- the invention has for its object to provide a solar module of the type mentioned above, which at low height and reduced manufacturing costs a reli ⁇ sige contacting between the solar cell contacts and the contact tracks on the support body ge strictlyrleis ⁇ Tet.
- the basic idea of the invention is that from ⁇ finally back contacts having solar cells, ie, solar cells first with purchasedbil ⁇ Deten only at the rear, parallel, alternating, linear plus and minus contacts, with arranged on a supporting body for the respective solar cell and second contact path rows, each of which is arranged in parallel at a distance of two plus or minus contacts in parallel and ent ⁇ speaking the plus and minus contacts of the solar cell aligned first and second contact tracks are electrically connected.
- the electrically connected to the back side ⁇ Plus contacts of the solar cell first contact paths with respect to the connected to the back print ⁇ term negative contacts of the solar cell second contact paths to the distance between two solar cells are arranged offset ⁇ contacts.
- the solar module formed in this way can be produced in a simple manner, that is to say with little expenditure of time, cost and apparatus. how to be manufactured with a reliable Kunststoffl für technik between the solar cell contacts and the contact tracks on the Trä ⁇ ger Economics, without risk of short circuit. It is also characterized by an especially important in small electrical appliances low height.
- the positive and negative contacts of the solar cell with the contact tracks of the carrier body each have two spaced arrange ⁇ te soldering points are connected to each other. Distortion of the solar module during the contacting is avoided, while a short-circuit contact is prevented by the soldering points due to the staggered arrangement of the contact ⁇ tracks on the support body despite the trained at a close distance So ⁇ larzellenfirme.
- the positive and Mi ⁇ nus giftede of the solar cell with the contact tracks can be connected to the carrier body by means of a conductive adhesive.
- the two Kon ⁇ clock train rows are each connected via a conductor track, which leads via a through-hole in the carrier body to at least one plus and one minus contact point on the free bottom of the solar module.
- a Abdecklack Mrs is formed on the inner and outer surfaces of the carrier body for the isolation of the contact paths and the conductor tracks of the solar module.
- the contact paths are wetted with solder ⁇ points or conductive adhesive.
- At least one to the Kunststoffbahnrei ⁇ hen aligned solar cell is formed with only the back side thereof, placed parallel line-shaped positive and negative contacts alternately and subsequent ⁇ xd the solder or the conductive adhesive is cured under Wär ⁇ meeinrial.
- the preparation can with simp ⁇ chen devices, that is, be carried out without the use of costly special machines.
- FIG. 1 shows a bottom view of a solar cell with strip-shaped contacts (rear side contacts) formed only on its rear side;
- FIG. 2 is a plan view of a carrier body of a solar module with two rows of contact paths to the
- Fig. 3 is a sectional view of a of a solar cell and a support body according to Figures 1 and 2 gebil ⁇ Deten solar module. and Fig. 4 is a detailed representation of a Sucuna ⁇ pers with the current paths for current collection.
- the p-layer is contacted through the n-layer, so that the positive and negative solar cell contacts (usually front side and back contacts) only on the in Fig. 1 visible back of the solar cell 1 are formed.
- the solar cell contacts form on the back of So ⁇ larzelle a pattern of a short distance, here 0.2mm, alternating juxtaposed, strip-shaped plus contacts 2 and negative contacts.
- the solar ⁇ cell 1 aligned - first and second - contact path ⁇ rows 4, 5 from each at a distance 2a between two plus contacts 2 or two negative contacts 3 of the solar cell 1 parallel to each other - first and second - contact tracks 6, 7 formed on a support body 8 ,
- the contact tracks 6 of the first contact track row 4 are arranged to the contact tracks 7 of the second contact track row 5 ver ⁇ sets, by the distance "a" between a positive contact 2 and an adjacent negative contact.
- Fig. 3 is a sectional view of a ten solar module aussente- for better Il ⁇ lustration only a single solar cell 1 shows 9.
- a solar panel 9 but a plurality of solar cells 1 on a carrier body 8 with a plurality of first and secondmaschinebahnrei ⁇ hen 4, 5 include, the respective plus and Minuskontak ⁇ te 2, 3 more groups of Victorbahn Herbertn 4, 5 kon ⁇ clock and are interconnected in a suitable manner.
- FIG. 1 is a sectional view of a ten solar module aussente- for better Il ⁇ lustration only a single solar cell 1 shows 9.
- a solar panel 9 but a plurality of solar cells 1 on a carrier body 8 with a plurality of first and secondmaschinebahnrei ⁇ hen 4, 5 include, the respective plus and Minuskontak ⁇ te 2, 3 more groups of Victorbahn Herbertn 4, 5 kon ⁇ clock and are interconnected in a suitable manner.
- Solar cell alternately trained +/- contacts which also has a ver ⁇ reduced height in comparison with the known solar modules, is ver ⁇ connected with little effort.
- a plurality of rows of contact lines are mounted on the carrier body and preferably with a cost-effective solder paste or wetted a conductive adhesive, and that due to the offset in two rows of contact tracks contact tracks without risk of short circuit.
- the production can - compared to the known methods for the production of solar modules with front and back contacts - largely automated without the use of special machines and therefore be carried out with reduced time and cost.
