Abstract
The invention discloses a kind of 3D lamination solar energy crystal silicon battery components.Component includes several solar battery strings arranged side by side, and any battery strings are not in the plane where two neighboring battery strings；Any battery the string direction of plane and two adjacent battery strings where perpendicular to two neighboring battery strings overlap, without invalid generating area between realization battery strings.Different battery strings are connected between electrode end to end by welding, can be with serial or parallel connection.In addition to welding connects between two adjacent cell strings, it is necessary to keep insulation, i.e. lap insulation in two adjacent cell strings.The present invention can be further reduced invalid generating area in component, improve the generated output density of photovoltaic module.
Description
Technical field
The present invention relates to solar photovoltaic technology field, specifically a kind of 3D lamination solar energy crystal silicon battery component.
Background technique
At present mainstream photovoltaic module use welding, multiple cell pieces are connected into battery strings, then by battery strings series connection or
Parallel connection, with hot melt adhesive（Mainly EVA）, there are also glass, the materials such as backboard are laminated together forms component, and all cell pieces are respectively positioned on
In same plane.Contact causes electric leakage etc. to consider that adjacent cell sector-meeting is at regular intervals, this will lead between cell piece in order to prevent
Spacing area becomes the invalid generating area of component.
Occurs a kind of " imbrication " or " lamination " formula photovoltaic module now, as described in CN105489684A, in same battery
Concatenated multiple cell pieces in going here and there, one end of every cell piece are placed in above adjacent cell piece, and the other end is placed in another adjacent electricity
Below the piece of pond, the anode of every in this way cell piece is all connected with another cathode using realizations such as welding or conducting resinls, different
There is still a need for a fixed spacing is kept between battery strings, connected with welding.Although the battery in same battery strings has part stacking,
All battery strings are still in same plane structure.Advantage is that welding usage amount, reduction current loss, raising pair can be reduced
The utilization rate of component area.But one side cell piece lamination techniques difficulty is higher；On the other hand, still there is big quantity space in component
It can not efficiently use.
Summary of the invention
It, can be with for the battery strings using traditional welding connection the purpose of the present invention is to provide a kind of 3D stacked wafer moudle
Very simple realization lamination；For laminated batteries string described in CN105489684A, the invalid generating area of component can be further reduced.
Technical scheme is as follows：
Several solar battery strings arranged side by side, any battery strings are not in the plane where adjacent cell string.
Any battery the string direction of plane and two adjacent battery strings where perpendicular to adjacent cell string have part weight
It is folded, without invalid generating area between realization battery strings.
Cell piece can also be connected using traditional welding connection structure using lamination in same battery strings in the present invention
Structure or other connection structures.
Different battery strings are connected between electrode end to end by welding, can be with serial or parallel connection.
Two adjacent cell strings are other than using welding connection between electrode end to end, it is necessary to keep insulation.That is two phases
Lap insulation in adjacent battery strings.
The beneficial effects of the present invention are the insulation laminations realized between battery strings, to reduce the invalid hair of photovoltaic module
Electric area can effectively improve the generating efficiency of photovoltaic module.
Detailed description of the invention
Embodiment in order to further illustrate the present invention, following accompanying drawings are briefly described the embodiment of the present invention.It is clear that
Drawings discussed below is only a kind of embodiment recorded in the present invention, is not being paid for those of ordinary skill in the art
Under the premise of creative work, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the floor map of battery strings arrangement in 3D stacked wafer moudle of the invention.
Fig. 2 is the side schematic view of battery strings arrangement in 3D stacked wafer moudle of the invention.
Fig. 3 is a kind of schematic diagram of specific embodiment of 3D stacked wafer moudle of the invention.
Specific embodiment
The present invention is described in detail for embodiment shown in reference to the accompanying drawing.
As shown in Figure 1, photovoltaic module front schematic view.Because the structure of photovoltaic module is routine techniques, no longer discuss here
It states, only explanation and general components difference, the i.e. laying method of battery strings and relative position.This figure only shows three batteries
String, is 01,02,03 respectively, and intermediate cell string 02 and two neighboring battery strings 01,03 have partial region A12 and A23 overlapping.
As shown in Fig. 2, the side view of the present embodiment.Battery strings 01,02 and 03 are arranged in isosceles triangle.01 and 02 and 02 He
03 battery strings lap can be separated by megohmite insulant.
As shown in figure 3, realizing one of the embodiment of the present invention to use a piece of hot melt adhesive film 001, it is preferred that this hot melt adhesive
Film 001 is EVA, and the isolation of adjacent cell string is opened.After lamination, insulation and the lamination of adjacent cell string can be realized.This
For hot melt adhesive film to be additional increased, actual component laminating technology need to use at least other 2 hot melt adhesive films, be respectively placed in battery strings
Above and below plane, because no longer illustrating as common process herein.
It should be noted that the present embodiment is not limitation of the present invention, those of ordinary skill in the art are according to these embodiment party
The equivalent transformation or substitution in the principle of work and power or structure that method is realized, all belong to the scope of protection of the present invention within.
