Detailed description of the invention
Fig. 1 is the schematic diagram of photovoltaic cell printing screen plate described in the utility model first embodiment.
Fig. 2 is the schematic diagram of photovoltaic cell printing screen plate described in the utility model second embodiment.
Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the utility model.On the contrary, they be only with such as
The example of the consistent device and method of some aspects be described in detail in the appended claims, the utility model.
It is only to be not intended to be limiting this reality merely for for the purpose of describing particular embodiments in the term that the utility model uses
With novel.In the "an" of the utility model and singular used in the attached claims, " described " and "the"
Most forms are intended to include, unless the context clearly indicates other meaning.It is also understood that term used herein " and/
Or " refer to and include that one or more associated any or all of project listed may combine.
It is in square as shown in Figure 1, providing a kind of photovoltaic cell printing screen plate 100 in the utility model first embodiment
Shape, and it is equipped with center line O, the printing screen plate is divided into symmetrical two printing zones α, β by the center line O, this two
A printing zone α, β are located at the two sides of the center line O, due to being arranged symmetrically in relation to each other, main below to describe wherein
The layout of one printing zone.
The printing screen plate has two side edges parallel with the center line O, and two side edges are in described
The distance of heart line O is identical, and described symmetrical two printing zones α, β are located at described two side edges and the center
Between line O, wherein be equipped with several subregions being parallel to each other in each printing zone, be respectively the region X, the region Y and the area Z
Domain, the region X, the region Y, Z region respectively from the center line O to the side edge be distributed, wherein the region X with it is described
Center line O is disposed adjacent, and the region Y departs slightly from the center line O, and the Z region is farther from center line O, closer to net
The side edge of version, i.e., from the region X, the region Y and Z region respectively towards separate center line O, by the direction arranged distribution of proximal.
Due to printing screen plate in printing process each time all can deformation occurs, largest deformation position is located at the center line O of printing screen plate
Position, printing screen plate is in the shape of the letter V along the center line O at this time, so when only symmetrical two positions printing is out of question simultaneously,
It just can be shown that the printing performance of slurry, this namely two printing zones α, β described in the utility model relative to center line O is in
Reason arranged symmetrically.
Specifically, the hollow out of several printing gate line electrodes is offered in the region X, in the region Y and in Z region
Mouth (not shown), and the width of the hollow out mouth in three sub-regions is different from each other, for being printed out respectively in three regions
Gate line electrode of different size, it is preferable that the width of three sub-regions is arranged are as follows: 18 μm < X < 24 μm, 20 μm < Y < 26 μm, 22 μm
< Z < 28 μm, and tri- regions described X, Y, Z amount to 15-60 hollow out mouth, 30-120 hollow out mouth of entire halftone can be printed out
30-120 gate line electrode both avoids design gate line electrode radical very few in this way, compares data distortion, while avoiding radical mistake
It is more, it causes to obscure when checking printing broken string.It is that can compare difference on halftone that trizonal purpose, which is arranged, in the utility model
The printing effect in region helps to select more appropriate halftone hollow out mouth in slurry volume production, or to screen different slurries
The ability of the printing strike through of material.
It is noted that being additionally provided with the 4th print on the printing screen plate other than the above-mentioned region X, the region Y and Z region
Circular hollow out mouth P1 there are two being set in brush area P, the 4th Printing Zone P, and this two circle hollow out mouth P1 are concentric circles setting,
For print out two be in concentric circles round gate line electrode, it is preferable that the inside circular diameter of the circle hollow out mouth is
1.0-6.0mm, outside circular diameter 3.0-16mm, diameter difference value 2-10mm between inside and outside circle.The 4th Printing Zone P is located at described
On the outside of Z region, and between the Z region and side edge.Moreover, be located at printing zone α in the 4th Printing Zone P be located at
The 4th Printing Zone P in printing zone β is also symmetrical set.In the utility model, the hollow out mouth of two concentric circles is set
The purpose of P1 is the gate line electrode in order to go out two concentric circles in photovoltaic cell surface printing, can be used to measure same
Resistance sizes under the same diameter of heart circle between inner circle and outer circle, convenient for comparing the engagement capacity between different slurries and silicon wafer,
Since inside and outside circle is relatively isolated, directly it is connected to without metal, for the method for measuring adjacent main grid resistance, concentric circles
Measurement method is more scientific.
Certainly, in the second embodiment of the utility model, as shown in Fig. 2, the area distribution of the printing screen plate is
Variation, specifically, the region X, the region Y and Z region remain unchanged towards far from center line O directional spreding, but the 4th Printing Zone P then with
The center line O is disposed adjacent, between the region X and center line O, the hollow out of two the 4th Printing Zone P inner circulars
Mouth P1 is symmetrical set also relative to the center line O.
As it can be seen that the utility model is distributed different line widths in the two sides center line O by the structure arrangement of improvement printing screen plate
Printing zone (i.e. hollow out mouth region of different size), can print out the gate line electrode of different in width, it is possible to reduce cell piece
The sheet resistance spread in processing procedure is very poor, while verifying influence of the screen painting deformation for printing effect.Moreover, it is also possible to by
Coating uses different emulsion on printing screen plate, or with a series of different model of emulsions, to compare with a slurry pair
The printing performance of different emulsions.Therefore, the printing screen plate of the utility model can aid in the best printing condition of determining slurry,
Research and development time and Material Cost is saved, the engagement capacity for comparing different system slurries that can be more accurate.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution, improvement and etc. done should be included in the utility model
Within the scope of protection.
