Embodiment
For make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, does detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
A lot of details have been set forth in the following description so that make much of the present invention; But the present invention can also adopt other to be different from alternate manner described here and implement; Those skilled in the art can do similar popularization under the situation of intension of the present invention, so the present invention does not receive the restriction of following disclosed specific embodiment.
Secondly, the present invention combines sketch map to be described in detail, when the embodiment of the invention is detailed; For ease of explanation; The profile of expression device architecture can be disobeyed general ratio and done local the amplification, and said sketch map is example, and it should not limit the scope of the present invention's protection at this.The three dimensions size that in actual fabrication, should comprise in addition, length, width and the degree of depth.
The invention provides a kind of on solar battery sheet the method for printed patterns, on the one hand pattern can be set on solar battery sheet, can not reduce on the other hand this day sun can the battery sheet electrical property.
Be described in detail through several specific embodiments below.
Embodiment one
Present embodiment provide a kind of on solar battery sheet the method for printed patterns, basic procedure is as shown in Figure 1, may further comprise the steps:
Step S11, printing back electrode and back of the body electric field.
Step S12, corresponding main grid line place is provided with pattern on the positive electrode half tone, this pattern apart from main grid line dual-side along certain distance.
Step S13, printing positive electrode stay the pierced pattern of corresponding said pattern at the main grid line place of positive electrode.
Step S14, oven dry positive electrode.
Step S15, sintering.
The embodiment of the invention is chosen on the main grid line pattern is set, as long as guarantee that pattern does not block the main grid line, just can not influence the electrical property of solar battery sheet, has realized on solar battery sheet, being provided with the effect of sign.
Below through object lesson supplementary notes.
Suppose that certain company need add the sign of " T " on solar panel; Then in advance on the positive electrode half tone corresponding main grid line place this pattern is set; So after finishing above-mentioned steps S102, can on silicon chip, form this sign, behind completing steps S105, can on silicon chip, form the sign on silvery white limit, the blue end.
This process can appear through Fig. 2, Fig. 3 and Fig. 4; Wherein, Fig. 2 is the positive electrode structural representation of prior art, this positive electrode by main grid line 1 with form with said main grid line 1 vertical secondary grid line 2, said each bar main grid line 1 is parallel to each other; Said many secondary grid lines 2 are parallel in twos, and said main grid line 1 is wideer than the width of secondary grid line 2; Fig. 3 is the structural representation of silicon chip positive electrode behind the embodiment of the present invention embodiment, and Fig. 4 is the enlarged drawing of label I among Fig. 3.From Fig. 3 and Fig. 4, can find out, carry out flow process shown in Figure 1 after, had sign T on the main grid line 1 in the silicon chip positive electrode structure.
Because this sign, therefore can not exert an influence to the transmission of main grid line current along also having a segment distance apart from main grid line 1 dual-side, in addition, can not increase the shading area yet.
In the above-mentioned flow process shown in Figure 1, the positive electrode printing belongs to normal process, just some variation of the figure of half tone.
