Abstract
The utility model relates to a crystalline silicon component with power increased through changing the width of interconnection strips. The component comprises a plurality of battery sheets and interconnection strips, wherein each battery sheet is provided with a main grid line, the main grid lines of the battery sheets are connected with one another through the interconnection strips, and the width of the interconnection strips is 0.1-0.3mm smaller than that of the main grid lines. Compared with the prior art, the crystalline silicon component has the advantages that insufficient soldering of the battery sheets is prevented, contact resistance value of the battery sheets and the interconnection strips can be reduced, and the generating efficiency of a solar battery can be further improved.
Description
Technical field
The utility model relates to a kind of solar cell parts, especially relates to a kind of passing through and changes interconnecting strip width and the crystalline silicon assembly of bring to power.
Background technology
The effect of interconnecting strip is every in assembly battery sheet to be cascaded mutually and an electric action, guarantees that assembly generates electricity smoothly.Crystal silicon solar interconnecting strip width is in the past set according to battery sheet main grid line width, yet in welding process, being coated with the tin layer and will running out of battery sheet main grid line through flatiron high temperature and shelter from battery sheet surface and influence power on the interconnecting strip, also play the rosin joint phenomenon easily, the power of assembly is descended if rosin joint appears in the battery sheet.
The utility model content
The purpose of this utility model is exactly to provide a kind of battery sheet rosin joint that can not cause for the defective that overcomes above-mentioned prior art existence, can reduce the contact resistance value of battery sheet and interconnecting strip, that can also improve solar cell power generation efficient passes through change interconnecting strip width and the crystalline silicon assembly of bring to power.
The purpose of this utility model can be achieved through the following technical solutions: a kind of passing through changes interconnecting strip width and the crystalline silicon assembly of bring to power, it is characterized in that, this assembly comprises multi-disc battery sheet, interconnecting strip, described battery sheet is provided with the main grid line, the main grid line of described battery sheet is together in series by interconnecting strip, and the width of described interconnecting strip is than the little 0.1～0.3mm of main grid line width.
The width of described interconnecting strip is than the little 0.2mm of main grid line width.
Compared with prior art, the utlity model has following advantage:
1, since the width of crystal silicon solar interconnection line less than battery sheet main grid live width, like this in welding process, the battery sheet has not just been blocked in being coated with the tin layer and just can not running out of battery sheet main grid line through flatiron high temperature on the interconnecting strip.Because the battery sheet is to rely on area size and conversion efficiency to come rated output, equal efficient area is high-power more just high more, otherwise just more little, and it is next to borrow by sunlight heat conversion just to send electricity, so the few more electricity that sends of the shelter of assembly is just many more.
2, the width of crystal silicon solar interconnection line helps lifting subassembly power and adds the strong weld fastness less than battery sheet main grid live width, can not cause battery sheet rosin joint, can also reduce the contact resistance value of battery sheet and interconnecting strip, with low its influence to the power of assembly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of passing through changes interconnecting strip width and the crystalline silicon assembly of bring to power, and this assembly comprises multi-disc battery sheet, interconnecting strip 1.The battery sheet is provided with the main grid line.The main grid line of battery sheet is together in series by interconnecting strip 1.The width of interconnecting strip is than the little 0.2mm of main grid line width.
The effect of interconnecting strip is every in assembly battery sheet to be cascaded mutually and an electric action, guarantees that assembly generates electricity smoothly, if rosin joint appears in the battery sheet power of assembly is descended.Customization crystal silicon solar interconnecting strip customized according to battery sheet main grid line width in the past, being coated with the tin layer and will running out of battery sheet main grid line through flatiron high temperature and shelter from battery sheet surface and influence power on the welding process interconnecting strip, also a rosin joint phenomenon easily.Now the width of customization crystal silicon solar interconnection line is less than 0.2 millimeter of battery sheet main grid live width, and being coated with the tin layer and just can not running out of battery sheet main grid line through flatiron high temperature on the welding process interconnecting strip just do not blocked the battery sheet like this.Because the battery sheet is to rely on area size and conversion efficiency to come rated output, equal efficient area is high-power more just high more, otherwise just more little, and it is electric next to borrow by sunlight heat conversion just to send.So the few more electricity that sends of the shelter of assembly is just many more.
Claims (2)
1. one kind is passed through to change interconnecting strip width and the crystalline silicon assembly of bring to power, it is characterized in that, this assembly comprises multi-disc battery sheet, interconnecting strip, described battery sheet is provided with the main grid line, the main grid line of described battery sheet is together in series by interconnecting strip, and the width of described interconnecting strip is than the little 0.1～0.3mm of main grid line width.
2. according to claim 1 a kind of the crystalline silicon assembly of bring to power is characterized in that by changing interconnecting strip width, and the width of described interconnecting strip is than the little 0.2mm of main grid line width.
