Abstract
The utility model provides a kind of solar panel and solar battery sheet thereof, and this solar battery sheet comprises silicon chip, is only provided with two parallel main grid lines on silicon chip, and described two main grid lines are separately positioned on two relative edges of described silicon chip.The utility model, by two parallel main grid lines are set on silicon chip, has not only reduced the cost of manufacture of solar battery sheet, and has increased the extinction area of solar battery sheet, and then can improve the operating efficiency of solar battery sheet.On the other hand, the negligible amounts of main grid line can reduce the consumption of welding used in the time of series-connected solar cells sheet, and then can reduce the cost of manufacture of solar panel.
Description
Technical field
The utility model relates to field of solar energy, more specifically, relates to a kind of solar panel and solar battery sheet thereof.
Background technology
In the production process of solar module, cell piece need to be together in series, and connecting between cell piece and cell piece need to be welded by welding, welding must be accomplished firm welding in the process of series cells, avoids occurring the generation of rosin joint, dry joint phenomenon.
But, current cell piece mostly is the cell piece of three grid formulas, like this, in the time of the cell piece of this three grid formula of series connection, the quantity of the welding that need to weld is more, both caused welding and scaling powder waste, increased production cost, increase again the probability that occurs rosin joint, dry joint, and then affected the stability of solar battery sheet work; Secondly, the main grid of the cell piece of three grid formulas is positioned at the zone line of silicon chip, like this, in the time that cell piece is carried out to laminating technology, is easy to produce fragment on cell piece.In addition, solar battery sheet contains more main grid can cause certain blocking to the extinction face of cell piece, thereby has reduced to a certain extent the operating efficiency of cell piece.
Utility model content
The utility model aims to provide a kind of solar panel and solar battery sheet thereof, with the solar panel that solves prior art because of the higher problem of the more cost of main grid quantity in solar battery sheet.
For solving the problems of the technologies described above, according to an aspect of the present utility model, provide a kind of solar battery sheet, comprise silicon chip, on silicon chip, be only provided with two parallel main grid lines.
Further, two main grid lines are separately positioned on two relative edges of silicon chip.
Further, main grid line comprises multiple spaced main grid sections.
Further, main grid section is rectangle.
Further, solar battery sheet also comprises: many auxiliary grid lines, be arranged on silicon chip, and auxiliary grid line is perpendicular to main grid line many supplementary gate line parallels.
Another aspect of the present utility model, provides a kind of solar panel, comprises above-mentioned solar battery sheet.
Further, two adjacent solar battery sheets link together by welding.
The utility model, by two parallel main grid lines are set on silicon chip, has not only reduced the cost of manufacture of solar battery sheet, and has increased the extinction area of solar battery sheet, and then can improve the operating efficiency of solar battery sheet.On the other hand, the negligible amounts of main grid line can reduce the consumption of welding used in the time of series-connected solar cells sheet, and then can reduce the cost of manufacture of solar panel.
Brief description of the drawings
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 has schematically shown the structural representation of the embodiment of the solar battery sheet in the utility model.
Reference numeral in figure: 10, silicon chip; 20, main grid line; 21, main grid section; 30, auxiliary grid line.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
An aspect of the present utility model, provides a kind of solar battery sheet, please refer to Fig. 1, and this solar battery sheet comprises silicon chip 10, is only provided with two parallel main grid lines 20 on silicon chip 10.
The utility model, by two parallel main grid lines 20 are set on silicon chip 10, has not only reduced the cost of manufacture of solar battery sheet, and has increased the extinction area of solar battery sheet, and then can improve the operating efficiency of solar battery sheet.On the other hand, the negligible amounts of main grid line 20 can reduce the consumption of welding used in the time of series-connected solar cells sheet, and then can reduce the cost of manufacture of solar panel.
Preferably, two main grid lines 20 are separately positioned on two relative edges of silicon chip 10.The relative edge that main grid line 20 is arranged on to silicon chip 10 can increase the extinction area of solar battery sheet effectively, and then can improve the operating efficiency of solar panel.In addition, arrange like this and can reduce the fragment that solar battery sheet produces in laminating technology, thereby can heighten the performance of solar battery sheet.
Preferably, main grid line 20 comprises multiple spaced main grid sections 21.
Preferably, main grid section 21 is rectangle.
Preferably, solar battery sheet also comprises: many auxiliary grid lines 30, many auxiliary grid lines 30 are arranged on silicon chip 10 abreast, and auxiliary grid line 30 is perpendicular to main grid line 20.
Another aspect of the present utility model, provides a kind of solar panel, comprises above-mentioned solar battery sheet.The consumption of the welding in this solar panel is less, and cost is lower.
Preferably, two adjacent solar battery sheets link together by welding.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
