Description
Technical field
The present invention relates to a kind of solar cell module, more particularly, to a kind of low cost high powered solar battery group
Part.
Background technology
Solar components have a kind of function of converting solar energy into electric energy, are a kind of works for making full use of solar energy
Tool.How efficient utilization solar energy is reached using relatively low cost, be a research direction in current industry.
Solar cell module be by safety glass, first encapsulation glue-line, solar cell lamella, second encapsulation glue-line with
And backboard is sequentially overlapped composition.Wherein, solar cell lamella includes multigroup solar cell string.Every group of solar cell string bag
Multiple solar battery sheets are included, the front of each solar battery sheet is provided with main gate line, and its back side is provided with back electrode, passes through
Successively be attached multiple solar battery sheets to form the solar cell string by interconnecting strip.Specifically, interconnection is passed sequentially through
With the back electrode of adjacent solar battery sheet be connected with each other the main gate line of previous solar battery sheet by bar.
Current solar battery sheet main gate line design width is 1.5mm, and the main flow interconnecting strip used in market is
1.6mm.Using this interconnecting strip weld after, have subregion block battery surface effectively receive source region, so as to reduce
The generating efficiency of solar components, while also can to a certain extent improve product cost.
The content of the invention
The purpose of the present invention is exactly to provide a kind of low cost high powered for the defect for overcoming above-mentioned prior art to exist
Solar cell module.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of low cost high powered solar cell module, it is characterised in that the battery component includes multi-disc cell piece
And interconnecting strip, described cell piece is provided with least 1 main gate line, and described main gate line is connected in series by interconnecting strip, described
Interconnecting strip width is equal with described main grid line width, is welded after described interconnecting strip is completely superposed with described main gate line
Connect in succession.
Described main grid line width is 1.5mm, and described interconnecting strip width is 1.5mm;Interconnecting strip width is more than main gate line
Cost can be caused to increase, while blocking battery component receives source region, reduce solar energy power output;Interconnecting strip width is less than
Its own resistance can be caused to increase during main grid line width, bring relatively high power to be lost, therefore interconnecting strip is set with main grid line width
It is set to equal, cost has been saved to a certain extent, while reducing self-resistance so as to reduce power attenuation, interconnection is prevented in addition
Bar blocks and source region is received near main gate line, improves solar energy power output.
Described interconnecting strip thickness is 0.25mm, it is contemplated that if interconnecting strip thickness crosses conference crushing cell piece during lamination, but
Interconnecting strip thickness is too small to cause current-carrying capacity to reduce, therefore both optimal selection 0.25mm comprehensive.
Described cell piece is additionally provided with a plurality of thin grid line, and described thin grid line is vertical with described main gate line to be connected, institute
The thin grid line width stated sets thin grid line and realizes collected current to greatest extent less than described main grid line width, while it is wide
Degree is set less than main grid line width so as to reduce shading-area, improves power output.
Described main gate line is provided with 2~5, sets the output work that more interconnecting strips are conducive to improving solar components
Rate.
Main gate line is provided with 3 on described cell piece, and battery component is inevitably resulted in while increasing main grid number of lines
Upper shading-area increase so that power output reduces, therefore is preferably provided with 3 main gate lines.
Compared with prior art, the present invention interconnecting strip width and main grid line width are set to it is equal, so as to reduce material
Usage amount, be effectively controlled the production cost of component, the another part that light source is blocked because reducing enables solar cell more
Many receives light source, can lifting assembly power output.
Brief description of the drawings
Fig. 1 is solar cell module structural representation of the present invention.
In figure, 1 is main gate line, and 2 is interconnecting strip, and 3 is thin grid line.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in figure 1, a kind of low cost high powered solar cell module, including multi-disc cell piece and interconnecting strip 2, institute
The cell piece stated is provided with least 1 main gate line 1, and described main gate line 1 is connected in series by interconnecting strip 2, and described interconnecting strip 2 is wide
Degree is equal with the described width of main gate line 1, and welding company is carried out after described interconnecting strip 2 is completely superposed with described main gate line 1
Connect.The wherein described width of main gate line 1 is 1.5mm, and the described width of interconnecting strip 2 is 1.5mm;The width of interconnecting strip 2 is more than main grid
Line 1 can cause cost to increase, while blocking battery component receives source region, reduce solar energy power output;The width of interconnecting strip 2
Its own resistance can be caused to increase during less than 1 width of main gate line, bring relatively high power to be lost, therefore by interconnecting strip 2 and main gate line 1
Width is set to equal, and cost has been saved to a certain extent, while reducing self-resistance so as to reduce power attenuation, prevents in addition
Only interconnecting strip 2 is blocked main gate line 1 and nearby receives source region, improves solar energy power output.The described thickness of interconnecting strip 2 is
0.25mm, it is contemplated that if the thickness of interconnecting strip 2 crosses conference crushing cell piece during lamination, but the thickness of interconnecting strip 2 is too small can cause current-carrying
Amount reduces, therefore both optimal selection 0.25mm comprehensive.Described cell piece is additionally provided with a plurality of thin grid line 3, described thin grid
Line 3 is vertical with described main gate line 1 to be connected, and the described width of thin grid line 3 sets thin grid line 3 less than the described width of main gate line 1
Collected current to greatest extent is realized, while its width is set less than the width of main gate line 1 so as to reduce shading-area, is improved defeated
Go out power.Described main gate line 1 is provided with 2~5, and described main gate line 1 is preferably provided with 3, increases 1 number of main gate line
Shading-area increase on battery component is inevitably resulted in simultaneously so that power output reduces, therefore is preferably provided with 3 main gate lines 1.
