Utility model content
The technical problem of the required solution of the utility model is: provide a kind of and can improve the whole power output of solar battery sheet, can reduce the solar battery sheet of solar battery sheet fragment rate in welding process simultaneously.
For addressing the above problem, the technical solution adopted in the utility model is: described solar battery sheet, its structure is: in the front of solar battery sheet, be evenly equipped with some spaced thin grid, front at solar battery sheet is also provided with some main grids, main grid intersects vertically and is communicated with thin grid, main grid arrives the electric current collection on the thin grid of each root together, and transfer out by the welding being welded on main grid, in the front of solar battery sheet, be evenly arranged at intervals with four main grids, the edges at two ends of every main grid all with the edges at two ends of the solar battery sheet distance at a distance of 3.5～4.5mm, four root bead bands cover respectively on the main grid being fused to separately, the top edge of welding is concordant with the top edge of main grid, the lower limb of welding stretches out from the lower limb of main grid, the welding length of extension is 1.04～1.07 times of main grid length, each described root main grid and the width of welding are 1.1 ± 0.1mm, the width of the described thin grid of each root is 0.06 ± 0.01mm, and the spacing between adjacent thin grid is 6 ± 1mm.
Further, aforesaid solar battery sheet, wherein, described welding is the painting tin red copper welding that copper content is greater than 99.96%, the yield strength of welding is 40～60MPa.
The beneficial effects of the utility model are: one, make the edges at two ends of main grid and the edges at two ends of solar battery sheet keep certain spacing, and the welding that makes to cover on solar battery sheet is only fused on main grid, in welding process, can leave the space of overflowing for the unnecessary scolding tin of piling up on welding, can also increase the area of dissipation of welding starting point and welding destination county simultaneously, minimizing solar battery sheet two ends are the cracked or hidden phenomenon of splitting because the inequality of being heated produces, and makes the fragment rate of solar battery sheet reduce by 10%～15%; Two, on the front of solar battery sheet, be evenly equipped with four main grids, and by regulating the specifications parameter of thin grid and main grid, thereby in the situation that the illuminating area of solar battery sheet remains unchanged substantially, greatly increased the contact point that is communicated with between thin grid and main grid, thereby greatly reduce the overall electrical resistance of solar battery sheet, improved the stability of power output, and when certain root or many thin grid are local occurs disconnecting when rosin joint phenomenon appears in phenomenon or welding and main grid and current loss can be reduced to 2% left and right, power output is compared has increased by 2%～3%.
