Organic solvent: including propylene glycol monomethyl ether, butyl acetate, alcohol ester 12, Tripropylene glycol monomethyl Ether
Mixture, weight be electrocondution slurry 5~7.5%.
Electrocondution slurry is prepared using following procedure:
1) prepared by two-period form co-activating organic carrier: under conditions of 30~60 DEG C of heating stirrings, by acroleic acid resin, second
Base cellulose, thixotropic agent and plasticizer are respectively dissolved in organic solvent (concentration is 5~50wt%).By having after above-mentioned predissolve
Machine raw material, dispersing agent and residual solvent stir 1~2 hour at 50~80 DEG C of Yu.After being cooled to room temperature, 400~500 are used
Purpose steel wire carries out processing collection.
2) above-mentioned carrier mixture is added in glass powder and silver powder, forms a paste composition after being sufficiently stirred.With three
Roller mill this paste composition of spreading repeatedly is ground to the electrocondution slurry that fineness (FOG) is 10~15/5~10 μm or thinner.
It the use of printing and time black speed is 400/800mm/ by above-mentioned electrocondution slurry obtained by screen printing technique
S is printed onto the SiN layer of silicon wafer substrate (156 × 156mm).Silk screen specification used be 430 mesh/13 μm wire rods/total thickness 33~
36 μm/be open as 17,20,23,26,29 μm (leptoprosopy opening) without net knot printing test halftone (Fig. 2).By cell piece red
It is dry in outer drying oven, then by being burnt into 40 seconds at 920 DEG C in belt firing furnace.Electrocondution slurry after roasting is cooling,
Form electrode.
The resistance value under halftone different openings is measured using resistance meter.
In comparative example, the grouping of organic carrier unlike above-described embodiment is heated after being divided into mixing, temperature range
It is 40~80 DEG C, stirring to dissolution.
In the present invention, in all embodiments and comparative example, in order to compare the different influence of carrier production method, use
The component and ratio of glass powder are consistent, as shown in Table 1 and Table 2.
Table 1
Table 2
Data explanation:
1. resistance value is lower, slurry strike through is represented, printing is good, is not likely to produce disconnected grid situation.
2. different glass component does not influence slurry strike through.
Using in the Examples 1 to 2 of two-period form co-activating carrier in electrocondution slurry, measurement resistance value is at 17~29 μm
The comparative example 1~2 that co-activating is not carried out in conventional process technique is below under opening respectively.
It chooses the highest comparative example 3 of battery conversion efficiency and is used as benchmark, and using real made of two-period form co-activating carrier
It applies example 3~5 to compare, forms electrode using identical silk screen and printing technology.Resistance is measured in the same manner as described above, is measured
Electrode width, and measure efficiency (EFF%).Under a light conditions, the solar battery of formation is placed in the Berger sun
For measuring efficiency in energy cell tester.Xenon arc lamp simulation in solar battery measuring instrument has the daylight of known strength
And width penetrates the light front surface in battery.Using four point contact methods measure about 400 load resistances setting under voltage (V) and
Electric current (I) calculates battery conversion efficiency (EFF) further according to this curve to determine the voltage-current curve of battery.
As shown in table 2, the embodiment 3 formed using same vehicle, in the case where electrical property and electrode depth-width ratio maintain,
Resistance value slightly improves, and especially improves under 17 μm of narrow opening more significant.Electrode width indicates that embodiment 5 is most narrow, electricity
High degree slightly rises.It is compared with comparative example 3, the efficiency of embodiment 5 is obviously improved, and can maintain lower resistance value, is shown
Show that the strike through performance of slurry also makes moderate progress.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
The electrocondution slurry prepared using two-period form co-activating organic carrier may be implemented the printing of graph thinning grid line, improve electricity
Pole depth-width ratio, and then cell conversion efficiency is promoted, and take into account good long-time printing and excessively ink, it is effectively improved solar energy
The production of cell piece.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
