Description

One kind cutting half-cell piece photovoltaic module

Technical field

The utility model belongs to photovoltaic processing technique field, and in particular to one kind cuts half-cell piece photovoltaic module.

Background technique

In general photovoltaic module cell piece connection type be mainly between cell piece series system be attached；With photovoltaic group Demand of the part industry to high power component cuts half-cell piece photovoltaic module and obtains cracking development, it is main to cut half-cell piece component It is carried out by the way of series connection and connection simultaneously in parallel, one kind as shown in Figure 1 typically cuts half-cell piece photovoltaic module, uses Cell piece is carried out being connected into a, b, c, d, e, f by required the piece number has 6 string battery strings altogether, then will wherein every two obtain in series and parallel again Battery strings group (a b, c d, e f), then again by each battery strings group connect, as shown in Figure 1, battery strings group a b, c d and e f Series connection.

Wherein, it needs to cross group using two (lead-out wire 2 and lead-out wires 4 in figure) using the component of Fig. 1 electric circuit diagram design The lead-out wire parallel diode of part length direction, lead-out wire 2 and lead-out wire 4, which cross component in laminated process, to be needed lead-out wire It pads on the cell piece of two strings battery strings (b battery strings and c battery strings or d battery strings and e battery strings) adjacent thereto, sees Fig. 2, Wherein the spacing between every string battery strings is L1, and the width L2 of lead-out wire is greater than battery strings spacing L1, sees Fig. 3, thus bring Technology controlling and process difficult point it is as follows:

(1) thickness of lead-out wire 2 and lead-out wire 4 has stringent limitation, and thickness is excessive or component will go out in lamination process Existing cell piece fragmentation, crack.

(2) it is needed between lead-out wire 2 and lead-out wire 4 and cell piece using one layer of isolated material 5, and isolated material 5 is subsequent Strict control is needed, and the use of isolated material 5 increases the difficulty operated when employee's lamination, influences to produce production capacity.

Utility model content

To solve the above-mentioned problems, the utility model provides one kind and cuts half-cell piece photovoltaic module, cell piece and extraction It does not need to insulate using isolated material between line.

The technical solution of the utility model are as follows: one kind cuts half-cell piece photovoltaic module, including cross component lead-out wire and Multiple series connections and the battery strings group arranged parallel, the battery strings group include at least two concatenated battery strings, adjacent electricity The distance between pond string group size is L1, and the distance between adjacent cell string size is L2 in each battery strings group, crosses component The width size of lead-out wire is L3, and wherein L1 is greater than L2, and L3 is less than L1.

Preferably, the battery strings group is 3.

Preferably, the battery strings group includes two concatenated battery strings.

Compared with prior art, the beneficial effects of the utility model are embodied in:

Component lead-out wire is crossed in the utility model to be between cell piece string string, it is contactless with cell piece, without using Isolated material insulation, not only simplifies technique, improves processing efficiency, and reduce the use of raw material, reduce manufacture Cost.
