Description
Technical field
The utility model particularly relates to a kind of metal warp and gold by braiding unlike material about a kind of printing screen plate
Belong to weft and is formed by printing screen plate.
Background technique
In the prior art, the structure of solar battery generally includes finger-like formula electrode (Finger bar) and full slice system electricity
Pole (Bus bar), and the design of most of solar batteries all uses very delicate " finger-like formula electrode ", effective coverage
Collected photoelectron is transmitted on bigger " full slice system electrode ", is then transmitted to again in the circuit system of component.In order to want
Increase the efficiency of solar battery, finger-like formula electrode is thin and high in design, and the height in this way in solar battery structure is wide
Relatively good, energy conversion efficiency is high.In the prior art, finger-like formula electrode is all orthogonal with full slice system electrode and with equidistant
Mode be distributed on silicon chip (wafer), as network technology processed improves, finger-like formula electrode is also increasingly thinner.
Screen painting it is a kind of in the prior art, a plurality of warp and a plurality of weft are first usually knitted to form a net
Cloth, (22.5 or 30 degree are differed) is fixed on a screen frame after the screen cloth is turned an angle again later, to form a halftone.Then,
It can be coated on the screen cloth and form a sensitive emulsion layer, recycle the mode of exposure development to be formed on sensitive emulsion layer later
Multiple patterns of openings.The purpose that the screen cloth is turned an angle is that multiple patterns of openings is made to avoid multiple warps and multiple wefts as far as possible
Alternate nodes.Finally, operator can scrape printing ink in turn using scraper pressure screen cloth, so that ink is schemed through multiple openings
Case stamps figure route (finger-like formula electrode) on printed material, achievees the purpose that printing whereby.
However, it is above-mentioned in the prior art, when warp and weft are woven into screen cloth, warp and weft are all using same
A kind of material, such as stainless steel, wolfram steel, and all openings and line footpath are all identical.After patterns of openings is formed, those patterns of openings
It often include the staggeredly node through, weft in the figure strike through area of finger-like formula electrode (patterns of openings be), those warps, weft
Staggeredly it is bad usually to will cause printing strike through for node.
Fig. 1 is a schematic diagram, to illustrate in the prior art for printing the mesh-plate structure of finger-like formula electrode.Please refer to figure
1, another kind shown in Fig. 1 is as in the screen structure of the prior art, in order to avoid being encountered in patterns of openings through, weft
Net knot, warp 121,123 system of weft are woven into screen cloth 12 in a manner of mutually perpendicular, and the screen cloth 12 formed is stretched and is fixed on
To form halftone 1 on screen frame 10.Wherein, sensitive emulsion layer 14 envelopes screen cloth 12, and includes multiple open on sensitive emulsion layer 14
Mouth pattern 16.Patterns of openings 16 is formed between two parallel warps 121, to avoid the net knot through, weft.
However, including weft 123 in patterns of openings 16, and between weft 123 and patterns of openings 16 in such a configuration
Angle be 90 degree.In this way, when ink is by 16 wire mark finger-like formula electrode of patterns of openings and when ink passes through patterns of openings
When weft 123 in 16, ink can be larger by the resistance from weft 123, thus after printing circuit ink height rise and fall it is big,
The finger-like formula electrode impedance for causing wire mark to come out will increase, and then influence the generating efficiency of solar battery.
Based on the above reasons, how to provide one kind has structure improved printing screen plate, makes to have in its patterns of openings
There is the net knot through, weft, and when ink passes through its patterns of openings can reduce impedance brought by warp, weft simultaneously, be wait solve
Item certainly.
