Description of the invention: [Technical field to which the invention pertains] A method of a solar cell capable battery having a front contact point. BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a front side and to a solar cell for use in the manufacture of the sun. [Previously] a solar cell constructed from a Shihwa wafer usually has a back contact on its back side and on its front side. The so-called previous contact. These pre-contacts ^ r, i collect electrons and connect the electrons (4) to the pieces. This type of connecting device 5 is an electrical wiring for relaying current or another - corresponding solar cell in a series circuit. To minimize shadowing, the front contacts are embodied in the form of thin contact fingers that are typically configured such that they are parallel to each other on the front side and extend at the same distance. Then, in order to connect the front contact to the connecting device, the flat line is provided, and the flat lines are electrically connected to each of the front contacts, laterally protruding beyond the solar cell and connected to the connecting device, and The masking of known flat lines is considered to be negative, and this is the area where the solar cells become active and thus also the efficiency of the solar cell. [Disclosed] - Problems and solutions • This month is based on the goal of providing a solar cell as mentioned in the introduction and a method suitable for a solar cell. By means of the solar cell and/or the method, the disadvantages of the prior art can be reduced, and the details This can increase the efficiency or yield of the solar cell. This problem is solved by the solar cell having the features of claim 1 and the method of manufacturing the solar cell having the features of claim 13 by 141070.doc 201003949. Advantages and preferred configurations of the invention are explained in more detail below with respect to the subject matter of the other claims. The wording of the claims is incorporated into the description by way of explicit reference. In the present invention, the present invention provides a connection line to be contacted from the front contact point. The connection lines are different in length and different from each other. ^^J degrees from the 5H connection device extension ^ or A plurality of contact fingers. At least some (better) of the connecting wires are electrically connected to the contact fingers a plurality of times over a length of two. This case means that the connecting wires are connected to different contact fingers multiple times in their longitudinal path. The distance that the connecting line is connected to the contact finger is equivalent to the repeating line for the connecting line. This is advantageous for a plurality of connecting lines or even for all connecting lines. Here, the present invention gives the connecting line a self-contained The contact of the front contact refers to the possibility of connecting the device multiple times. With the help of the connection line that leads to the connection device: only a few wires travel to the farthest distance:: touch The closer the connection is to the connecting device, the more the connection line can be used to deliver electrons to the connection benefit (ie, α卩 is used to carry current). Therefore, it is possible to distance the distance between the device and the available wire cross section. Basically reach two: the opposite line Relationship. This situation therefore means that the entire guide ▲, the surface is enlarged, the closer the contact finger will be to the connecting device. Therefore, it may be considered that it is advantageous in the case of the present invention that the current becomes larger 7 & stomach 'Yi Yu # near connection device. Therefore, in order to adapt to the general or expected power intensity and 4 indeed make the wire cross section required for this current intensity available (but already) so the front side of the solar cell is covered by the wire The region 141070.doc 201003949 can be reduced or reduced to the minimum necessary amount. In an advantageous configuration of the invention, the front joints are parallel to one another and extend at equal distances. Particularly advantageously the 'connecting line is at right angles to the front joint or the contact finger The phase library, the ground extension, not only achieves a simpler manufacturing but also achieves as much as possible the length of the connecting line of the solar cell and thus the shielding as much as possible. The connecting lines are also advantageously parallel to each other and particularly advantageously extend at the same distance.

It is especially advantageous to contact all of the three contact fingers in each condition. For individual connecting lines, it is particularly advantageous for all connecting lines having this length or possibly also for all connecting lines in general, this spacing is advantageously always the same. Adjacent connecting lines are advantageously connected to different contact fingers. In order to be able to conduct the most possible current conduction while reducing the number of connections from the connection line to the contact fingers, it is possible to provide a collective connection in which two to four contact fingers are connected to each other. This collective wiring can be fabricated on the front side by metallization (i.e., significantly easier than coating and joining the wires) in a manner similar to contact fingers during the manufacturing process of the solar cell. This collective wiring is advantageously extended in a manner similar to the front contact (i.e., 'with a very small cross section and at right angles to the contact fingers or in the same direction as the connecting lines) depending on the type and the actual target and manufacturing. Particularly advantageously, the collective connection causes three mutually adjacent contact fingers to be connected to each other' and the connection line is in contact with the collective connection or the connection line is connected to the collective connection 0 141070.doc 201003949 In the present state of the invention, the connection (4) Connected to the intersection with the contact finger and the second, 、, and set. The connected area is here for the largest area of the connection. Since the collective wiring and the connection line are located above the other, the shaded area of the solar cell is also reduced. There are various possibilities for connecting the connection, (4) to the connection (4) or the collective wiring system mentioned above. Welding or wire bonding is considered to be advantageous, two of which can be tried and tested technically, and can also be carried out on an industrial scale or in an automated manner. In a further configuration of the invention, a plurality of connecting lines each having the same length can be assumed, in particular by solar cells forming a so-called wiring group. (d) utilizing the fact that discrete length jumps are provided at the length of the distance between the two contact fingers relative to each other in the case where the length of the connecting line is from the connecting device toward the contact. Therefore, it is easy to divide the connecting lines having the same length into a common wiring group. The solar cell then has a plurality of wiring groups each having a connecting line of exactly different lengths. In this case, it is considered advantageous if at least three connecting lines are provided per wiring group. Furthermore, it may be advantageous to provide at least three such wiring groups. For example, conventionally used solar cells have 66 contact fingers. Assuming the above mentioned provisions of the collective wiring and assuming that the connecting lines do not terminate at each contact finger level due to collective wiring, for example, 33 or 22 wiring groups may be provided. Each wiring group then has two to four or even more connecting lines. In yet another configuration of the invention, it is possible to form connecting lines of different lengths with different cross sections. Under this circumstance, it can be assumed that the cross section of the connecting line increases as the length of the connecting wire increases, and the wear facing the line advantageously maintains the same 141070.doc 201003949. Therefore, it will be considered that the connection line may also carry a higher current density as a whole due to the larger length of the connecting line. However, it is advantageous to use only the same connecting line, which contributes to supply complexity and also contributes to fixing. The diameter of this connecting line can advantageously be in the range of 5 〇 pm and 1 mm. A diameter of from 200 μηι to approximately 300 μηη is provided in a particularly advantageous manner. Accurately in the case of the number of contact fingers and connecting wires mentioned above on the solar cell, combined with minimized shading, this actually results in a sufficiently high wire cross section. In a further development of the invention, it is considered advantageous if the connecting line has a substantially circular cross section. Although the reduced shading can in principle be achieved by a flat and upright cross section (where the cross section remains the same), in some cases, for the correct connection of the connecting line to the connection of the connecting line to the solar cell or contact finger The device has a large increase in complexity. In addition, the cost and manufacturing complexity are the lowest for lines with a circular cross section. The connecting wires may be composed of a material that is easily electrically conductive, such as sho, copper, silver or gold. Advantageously, W is used to cover the connecting lines with a corresponding coating for better purity and better solderability. The connecting wires are advantageously (4) or provided with solder (for example, 62 Sn/36 Pb/2 Ag). At the side of the solar cell facing the connecting device, the connecting line can be defined in an amount to follow the material to the workpiece. In addition to wire bonding, it is mainly technically simpler to solder. These and other features are not only apparent from the Shenjing Zhijia patent, but also from the description and the schema. 'Some of the characteristics can be realized and can be expressed as beneficial and essentially 141070.doc 201003949 α :蒦The embodiments of the invention are claimed herein (in each case, a plurality of sub-combinations, either individually or in the form of sub-combinations in the embodiments of the invention and in other fields). Dividing an application into individual chapters and subheadings does not constrain the statement based on its general validity under individual chapters and subheadings. [Embodiment] Exemplary embodiments of the invention are schematically illustrated in the drawings and are explained in more detail below. Fig. 1 shows an excerpt of a solar cell u in an oblique view. The solar cell u is basically constructed from the wafer <2> and its upward facing front 13 is visible. The electrical connection device 14#, for example in the form of an electrical conductor (in the manner of conduction current or the like), extends alongside the solar cell u. In order to collect electrons at the front side 13 of the solar cell 11, a contact finger 15 is provided. The contact fingers 15 are thin metal conductors which may also be applied directly to the front side, or even partially into the front side, by means well known to those skilled in the art. The contact fingers 15 are the same 'relative to each other' and are parallel to each other. Next, in order to connect the contact fingers 15 to the connecting device 14, a connecting line 18 is provided. These connecting lines 18 all start from the connecting means 14, but have different lengths, so they extend to different degrees to the front side 13 of the solar cell u. Although the end of the connecting line pointing to the left side is relatively accurately carried on a contact finger or passed as far as the contact finger 15, at the same time the connecting line i8 extends not only to the end of the left side to the solar cell or On the contact finger 15, the connecting line 18 is repeatedly connected to the solar energy 141070.doc 201003949 battery 11 or contact finger 15 by the distance of the three contact fingers 15. As a result, the route (c〇urse) gets a waveform type, which is quite inconspicuous in practice. A collective wiring 16 is provided which can in principle be manufactured in the same manner as the contact fingers 15 themselves. The collective wiring 16 is thus a short conductive conductor #, and here two contact fingers 15 are connected in each case. Collective wiring 丨 6 with the connection line! 8 The same way as the contact finger 15 extends substantially (four). Money Wiring _ Conductively connected to each contact finger that it traverses or covers. At the connection location 19, the connection line i 8 is electrically conductive to the collective connection 16 and the contact fingers 15 at each location in each condition. This can be seen by wire bonding or soldering. As can be seen only to a limited extent by Figure j, the connecting lines do extend over the collective wiring 16 so that the required amount of shielding remains as much as possible / J> In the plan view of the solar cell ii according to Fig. 2, in order to clarify the legend or the structure, the connecting line 18 is said to be a straight line (the connecting line is financially a straight line in the plan view), regardless of the side view according to Fig. 1. The squatting 4-wave route. However, in practice, where appropriate deviations from the embodiment, the collective wiring 16 of Figure 2 is illustrated as being slightly curved, while in practice or practice the 'collective wiring 16 is embodied as a straight line and as close as possible to the contact fingers 15 .angle. • The basic death of the solar cell in Figure 2 should also be understood as Woyi (4). A suitable solar cell has more contacts 15 and contacts #曰15: (for example) as mentioned above. Similarly, more than 24 instructions are provided in the visibility of solar cell 1. Fingers $. The connection line 18 is divided into three groups 21a, 21b, and .... In each of these groups 141070.doc 201003949 2 1 , the longest connection line 8 extends as far as the top Two contact fingers 15, and the shortest connecting line 18 extends as far as the second contact finger 15 at the bottom. The length gradient of the individual connecting lines 18 in one of the groups 21 is in each case The distance between the two contact fingers is three times. Therefore, there are also eight connection lines 18 groups having the same length, respectively, of which there are three such connection lines 18 in each of the groups. The difference in the formation of 21a and 21b is the distance along the connecting line 18 between the collective wires 16. Although in the left group 2丨a, the distance between the collective wires 16 along the longest connecting line 18' and its length are such that A contact finger 15 is connected to the connecting line 18, but this is different in the central group 21b. Thus, the distance between the collective wires 16 along the connecting line 18 is directly increased by the distance between the two contact fingers 15. Of course, this can also be changed for a plurality of connecting lines of one of the groups, such that The distance between the collective wires 16 and thus the resulting connection location 1 between the connector wires 18 and the collective wires 16 or contact fingers 15 is not necessarily equivalent for each of the wires in the group. It is possible to collectively wire 16 separate paths of the contact fingers 15, which have been omitted in the right group 2 1 c. It is also apparent that the length gradient of the connecting lines 18 need not be as illustrated in Figure 2. It is desirable, for example, to be distributed in a manner that is as uniform as possible such that the length difference between two mutually adjacent contact fingers is five to eight times the distance between the two contact fingers. It is easy to discern that the available conductor cross-section is generally extremely small in the condition of the contact fingers 15 away from the connecting means 14. Here, only one to three of the equal length connecting wires 8 are present. Close to the connecting device 141070.doc -10- 201003949 ,by Flowing and expanding the number 14, there are six to eight relatively short connecting lines 18. However, the current that will be transported away is quite large here, and this total conductor cross section is actually necessary. The current intensity (which increases, the closer to the connector cross section (4) (four) square cut), the ratio of turbulence intensity to the conductor cross section -5 ^ kg is kept the same regardless of the distance: the distance to the connected state 14 One of the main advantages of this month
