The transformation efficiency improving solar cell is a main target of current solar cell research, except the improvement of the selection to cell substrate material, substrate manufacture craft, make the electrode of solar battery of excellent performance and take suitable printing process also can improve the transformation efficiency of battery.
As the important step that crystal silicon cell makes, the performance of printing quality on final cell piece of electrode of solar battery printing has very large impact.And the factor affecting printing quality is except the destabilizing factor that printing machine exists, the performance of Printing screen itself has also had a strong impact on final printing quality.Traditional battery electrode printing process adopts common web plate to carry out one or many printing, and it mainly exists following defect problem:
1, easily there is empty print (i.e. breakpoint) in one-step print, and the depth-width ratio of thin grid line is little;
Although 2, repeatedly printing can avoid empty print, thin grid line seriously broadens, and affect battery illuminating area, and the result of repeatedly repeating print is thin grid line out-of-flatness, there will be at " camel peak ".
Therefore, this kind repeatedly mode of printing not only cost is high, and do not bring corresponding benefit, be not suitable for the Produce on a large scale of enterprise.So the problem that industry needs solution badly develops research, provide a kind of and make Printing screen rational in infrastructure and adopt corresponding suitable printing process to solve above-mentioned problems of the prior art.
Summary of the invention
For solving the problem, the object of the present invention is to provide and a kind ofly solve the defect existed in currently available technology, to improve electrode of solar battery Printing screen and the printing process thereof of the transformation efficiency of solar cell.
For achieving the above object, technical scheme of the present invention is:
A kind of electrode of solar battery Printing screen, include main gate line and thin grid line, this electrode of solar battery Printing screen is provided with grid line complementary structure, wherein, its non-active area is provided with for as the mark distinguishing web plate direction, the arrangement mode of the thin grid line bridging of described web plate is set to: by the mark distinguishing web plate direction of mark, by web plate in web plate plane after the central rotation 180 ° of web plate working region through accurate contraposition, the bridging locations complementary of thin grid line before making bridging in the thin grid line of postrotational web plate and rotating.
Further, the thin grid line bridging of described web plate is splayed bridging.
Further, the thin grid line bridging of described web plate is the bridging be parallel to each other.
Further, distinguish described in that the mark system in web plate direction by arranging both forward and reverse directions or arrow represents on web plate.
Adopt a printing process for electrode of solar battery Printing screen of the present invention, comprise the steps:
The first printing is carried out to silicon chip;
After the first printing, dry, after oven dry, carry out the second printing; Wherein, in second printing process, the position that Printing screen is original relative to silicon chip, web plate plane have rotated 180 °;
Finally dry again, sinter.
Further, in second printing process, on the in-plane that web plate contacts with silicon face, according to the both forward and reverse directions mark that web plate is arranged, Printing screen is rotated 180 ° relative to original position, silicon chip keeps primary print direction.
Further, in second printing process, on the in-plane that web plate contacts with silicon face, according to the direction arrow mark that web plate identifies, silicon chip is rotated 180 ° relative to the position of original silicon chip, Printing screen keeps primary print direction.
Due to the grid line complementary structure that Printing screen of the present invention is special, according to printing process of the present invention, the thin grid line of first printing rear electrode there will be at " the camel peak " that go out shown by traditional printing mode, but through the second printing, " camel peak " just can disappear; The gate electrode line uniform ground obtained after twice printing, and depth-width ratio is large, also solves empty print problem simultaneously, improves the transformation efficiency of solar cell.
