Description
Technical field
The present invention relates to the manufacturing technology necks that one kind can be used for the conductive silver paste of silk-screen printing, especially silicon solar cell
Domain, especially a kind of organic system for hachure high aspect ratio screen printing sizing agent.
Technical background
Silk-screen printing technique is the important process in silicon solar cell production process, and each electrode is needed using screen printing
Electrocondution slurry is printed on silicon wafer and is made after sintering process by dataller's skill.Since silk-screen printing is pile line operation, this
Slurry used in requiring keeps stable viscosity, good off line property and moulding in continuous and long-time printing
Property.
Conversion ratio is the most critical index for evaluating solar battery, and the higher the better for conversion ratio, in various raising slurries and is turned
In the scheme of rate, reducing line thickness, improving the height of lines is to improve the aspect ratio (thickness of electrode/electrode line width) of lines
The way that short circuit current is mainstream is promoted to reduce the series resistance of cell piece.More specifically, when the line thickness drop of printing
It is low, it is capable of increasing the light-receiving area of cell piece, while the elevated height of lines, the string resistance of cell piece is can reduce, guarantees electric current
Effective flowing, to promote the transformation efficiency of cell piece.
In face of above-mentioned requirements, the production firm of solar battery sheet is constantly reducing the width of thin grid when printing cells
Degree, is reduced to 28 μm from 35 μm of openings, so that 24 μm of openings.With the reduction that printing screen plate is open, the requirement to slurry is got over
Come higher.Thinner opening, it is desirable that slurry has good off line property, and network blocking phenomenon otherwise can occur, influence normally to produce；It wants
Slurry is asked to keep certain viscosity under high speed printing shearing, it is existing that too low viscosity can make the line edge of printing that diffusion occur
As influencing conversion ratio；It is required that there is slurry good plasticity to have enough height with the lines for guaranteeing printing, to reduce slurry
The series resistance of material promotes short circuit current；It also requires slurry to have certain levelability simultaneously, guarantees after finishing printing, slurry
Upper surface can automatic levelling, be not in height rise and fall the phenomenon that, to guarantee the performance of slurry.
And current electrocondution slurry can not also meet above-mentioned requirements comprehensively, mainly there is also one for slurry organic system system
Fixed deficiency, a large amount of slurry use the cellulose system of different series, different viscosities, lead to viscosity, the moulding of slurry
It can not be perfectly balanced between property and off line property three.In addition, in the prior art, vinyl chloride-vinyl acetate resin has been commonly used in halogen low-temperature setting
In type silver paste, the use technique of this silver paste is 150 DEG C of low-temperature bake solidifications, and the use technique of crystal silicon solar silver paste is
780 DEG C of high temperature sinterings, both silver pastes are essentially different, and low-temperature solidified silver paste can not make in manufacture of solar cells
With.

In view of the problems of the existing technology, the present invention provides a kind of be applicable in using vinyl chloride-vinyl acetate resin as resin system
In the electrocondution slurry organic system of hachure high aspect ratio silk-screen printing.The electrocondution slurry of organic system preparation disclosed by the invention
Possess good off line property, excellent plasticity, can be suitable for the 430/13 of minimum 28 μm openings has net netting version, while energy
Enough be suitable for minimum 22 μm opening without net knot version printing, printing is excellent, and print after lines it is with higher in length and breadth
