Embodiment 1

[0057] see figure 1 As shown, a method for automatic wiring of solar cells according to an embodiment of the present invention, a method for automatic wiring of solar cells, includes the following steps:

[0058] S1: Get the shape of the solar cell, for example image 3 As shown, obtain the shape of an irregular solar panel. Among them, there are many methods of acquisition, for example: providing four-point coordinates, side stakeout, or using 3dm, iges, dwg, etc. to directly import 3d graphic files.

[0059] S2: Establish an X-Y coordinate system, and obtain the upper side e1, lower side e2, left side e3 and right side e4 of the solar cell under the coordinate system, such as Figure 4 shown in .

[0060] S3: According to the size requirements of the bus, obtain the offsets d1, d2, d3, and d4 corresponding to the four sides of the solar cell. In this embodiment, the value of d1 is 4.9 mm, the value of d2 is 4.5 mm, and the value of d3 is is 8mm, and d4 takes the value of...

Embodiment 2

[0066] As an embodiment of the present invention, on the basis of the above-mentioned embodiment 1, between steps S5 and S6, the following steps are also included:

[0067] S51: Draw a circular arc structure at the junction between the horizontal wire and the bus wiring area, that is, the opposite side of the vertical wire (ie, the left e3 or the right e4).

[0068] According to the automatic wiring method of solar cells, drawing the arc structure of the connection between the bus wiring areas according to the above steps can reduce the hot spots caused by the high resistance value at the intersection of the wires.

Embodiment 3

[0070] As an embodiment of the present invention, on the basis of the above-mentioned embodiment 2, as Figure 5 As shown, in the step S51, the specific method of drawing the arc structure is: set the radius as R (in this embodiment, the value of R is 0.2mm), make a parallel line that is R at a distance from the horizontal wire, and make the distance inwards The opposite side of the vertical conductor is the parallel line of R, and the intersection point of the two parallel lines is the center of circle, and a circle with a radius of R is tangent to the opposite side of the vertical conductor and the horizontal conductor to obtain four points of tangency a, b, c, d, the arc between the tangent points a and b and the arc between the tangent points c and d are arc structures.

[0071] According to the automatic wiring method for solar cells, according to the above steps, the arc structure corresponding to the horizontal wire can be automatically obtained, avoiding the cumbersome...

Abstract

The invention relates to an automatic wiring method and an automatic wiring system for solar cells. The automatic wiring method includes creating coordinate axes to obtain coordinates of starting points of four sides of each solar cell and coordinates of end points of the four sides of each solar cell; setting corresponding shifting quantities, shifting the four sides of each solar cell according to the corresponding shifting quantities, and processing new graphic sizes and the sizes of original cells to automatically obtain bus wiring zones of the cells; determining wiring zones of horizontal guide wires, known widths W of the horizontal guide wires and distances L among the adjacent horizontal guide wires to automatically draw the horizontal guide wires and improve the horizontal guide wire designing efficiency; correspondingly translating the left side or the right side of each solar cell by a certain distance K according to set widths K of vertical guide wires to automatically obtain a new side; connecting the horizontal guide wires with the vertical guide wires to complete an automatic wiring step for the solar cells. The new sides and the original sides are combined with one another to form quadrangles which are the vertical guide wires of the horizontal guide wires.

Description

technical field [0001] The invention relates to an automatic wiring technology. Specifically, it relates to a solar cell automatic wiring method and system. Background technique [0002] As solar cell technology continues to develop, so does the efficiency of solar cells. As a new type of solar cell, thin-film solar cells mainly have three technical routes: amorphous / microcrystalline silicon (Si), cadmium telluride (CdTe) and copper indium gallium selenide (CIGS). The flexible thin film solar cell is to prepare the front electrode layer, the photoelectric conversion layer, and the rear electrode layer sequentially on a flexible substrate (usually a stainless steel sheet), and then in the process of connecting single cells in series, the flexible thin film solar cell produced in rolls needs to be cut into Rectangular single piece, and then the coating layer of the single piece is covered with connecting wires to collect and conduct electrons. The connecting wires are specif...
