Abstract
The utility model relates to an easily weld solar wafer, including battery piece body, the vertical setting main grid line on the battery piece body, the horizontal setting vice grid line on the battery piece body, the main grid line with vice grid line electricity is connected, interval distribution has the pore area on the main grid line, the pore area has the range of a plurality of fretwork holes to form. The utility model discloses well fretwork hole makes the unsmooth appearance of the main grid line surface formation rule that the printing came out, can effectively increase the area of contact who welds area and main grid line, increases the welding pulling force of main grid line. And utilize the sunken face in fretwork hole, weld during the welding and take molten metal tin and in filling process, along with the figure forms the extrusion effect by wide narrowing down, reinforce contact action power to reduce the printing figure of the consumption of positive silver -colored thick liquids.
Description
Technical field
The utility model relates to field of photovoltaic technology, and particularly one easily welds solar battery sheet.
Background technology
Solar battery sheet front main electrode is along with process modification and the requirement reduced costs, the narrowed width of main grid, effective contact area that welding rod welds with main grid is decreased while minimizing front lighting shines shielded area, reduce welding pulling force, affect the reliability and stability of assembly, and shortening assembly useful life, the main gate line of whole piece easily shuts out the light simultaneously.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide one and easily welds solar battery sheet.
The utility model solves the technical scheme that its technical problem adopts: one easily welds solar battery sheet, comprise cell piece body, be longitudinally arranged on the main gate line on described cell piece body, the secondary grid line be horizontally installed on described cell piece body, described main gate line is electrically connected with described secondary grid line, it is characterized in that, poriferous zone spaced apart in described main gate line, described pore area has the arrangement of multiple hollow hole to form.
In above-mentioned design, hollow hole makes the concavo-convex pattern of the main gate line surface formation rule printed, and effectively can increase the contact area of welding and main gate line, increase the welding pulling force of main gate line.And utilize the concave face of hollow hole, during welding on welding molten metal tin in the filling process, along with figure narrows from the width formation squeezing effect, strengthening contact action power, and reduce the printed pattern of the consumption of positive silver paste.
As the further improvement of the design, described hollow hole is circular, is convenient to processing.
As the further improvement of the design, described hollow hole is equilateral triangle, increases the welding pulling force of main gate line further
As the further improvement of the design, the height of described hollow hole is 0.15mm, and the distance between adjacent two the hollow hole centers of described longitudinal direction is 0.3mm, and the distance between adjacent two the hollow hole centers of described transverse direction is 0.25mm.Be convenient to process and effectively can increase the welding pulling force of main gate line.
The beneficial effects of the utility model are: in the utility model, hollow hole makes the concavo-convex pattern of the main gate line surface formation rule printed, and effectively can increase the contact area of welding and main gate line, increase the welding pulling force of main gate line.And utilize the concave face of hollow hole, during welding on welding molten metal tin in the filling process, along with figure narrows from the width formation squeezing effect, strengthening contact action power, and reduce the printed pattern of the consumption of positive silver paste.
