Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Composition graphs 1 and Fig. 2, Fig. 1 are the electrode of solar battery mesh-plate structure schematic diagrames without auxiliary grid line in prior art, and this web plate is electroforming web plate, and this electroforming web plate is electroformed nickel web plate usually.Compared to Figure 1, as embodiments provided a kind of electrode of solar battery Printing screen with auxiliary grid line 30 in Fig. 2, this Printing screen 1 is provided with many auxiliary grid lines 30 above; Auxiliary grid line 30 is parallel to the thin grid line 10 on electrode of solar battery Printing screen.The present embodiment is to after electrode of solar battery Printing screen 1 adding many auxiliary grid lines 30, the broken string probability of the thin grid line 10 of solar energy electrode Printing screen greatly reduces, the corresponding increase of electroforming print pass that it can be realized, namely the life-span of Printing screen is elongated, thus can greatly reduce printing cost.
In the present embodiment, preferred auxiliary grid line 30 is even number bar, and be symmetrically distributed in the both sides of the workspace residing for thin grid line 10, it is divided into 2 parts, and the number of preferred auxiliary grid line 30 is 2-20 bar.Spacing between auxiliary grid line 30 is equal, and it can be 0.5 ~ 3 times of the spacing between thin grid line 10.Meanwhile, as shown in Figure 2, the length of auxiliary grid line 30 is longer than the length of thin grid line 10.
As shown in Figure 2, this electrode of solar battery Printing screen 1 have 14 auxiliary grid lines.A kind of preferred embodiment for the spacing between auxiliary grid line 30 is equal with the spacing between thin grid line 10.And on Printing screen anchor point 20 both sides auxiliary grid line 30 between spacing and the size of anchor point 20 adapt, to dodge the anchor point 20 on Printing screen 1.As shown in Figure 4, Fig. 4 is a kind of supplementary gate line structure enlarged diagram of the part of Ι shown in Fig. 2.Width between described auxiliary grid line 30 is 75um.
