Description
Technical field
The present invention relates to solar cell preparing technical field, more particularly to a kind of sun without net knot printing
Can battery preparation technique.
Background technology
Solar cell is also known as " solar chip " or " photocell ", is a kind of photoelectricity using the sunshine direct generation of electricity
Wafer, as long as the illumination that it is satisfied certain illumination conditions is arrived, moment output voltage and can have the situation in loop
Lower generation electric current, physically it is being referred to as photovoltaic (Photovoltaic, being abbreviated as PV), abbreviation photovoltaic, its work original
Manage to convert optical energy into electric energy using photovoltaic effect, when solar irradiation is in semiconductor P-N junction (P-N Junction),
New hole-electron is formed to (V-E pair), in the presence of P-N junction electric field, hole flows to P areas by N areas, and electronics is by P areas
N areas are flowed to, electric current is just formed after connecting circuit.Due to being to be converted into solar energy using the photovoltaic effect of various potential barriers
The solid semiconductor device of electric energy, therefore also known as solar cell or photovoltaic cell, are the important of solar array power-supply system
Component.Solar cell mainly has crystal silicon (Si) battery, III-V semi-conductor cell (GaAs, Cds/Cu2S, Cds/CdTe,
Cds/InP, CdTe/Cu2Te), no machine battery, organic battery etc., wherein crystal silicon solar batteries occupy market mainstream leading position.
The stock of crystal silicon solar batteries is p type single crystal silicon of the purity up to 0.999999, resistivity more than 10 Europe centimetre, bag
Include the parts such as front matte, front p-n junction, front surface antireflection film, positive backplate.
Cell piece front side conductive silver paste serves collected current and conducts the effect of electric current, is weight in cell piece production cost
The part wanted, the front electrode typography of existing solar cell are the silk-screen printing of mature, traditional silk printing screen
Version be by screen cloth after certain pulling force stretching, be adhered on screen frame, then felt after pretreatment removes grease, impurity
Optical cement is coated with, and is solidified through printing down, flushing of developing forms pattern.
On the one hand the function of screen cloth is to be used to support photoresists, form pattern；On the other hand it is the transit dose for adjusting slurry.
Screen cloth is alternately to weave to form by the grenadine of latitude and longitude, and the material of grenadine is mainly by polyester fiber, nylon fiber, metal material
Matter or composite etc. are formed.Screen cloth is after certain tensile elongation, or is directly bonded on screen frame and forms half tone, or by multiple
Close technique and be fabricated to composite halftone.
But with the further raising that the industries such as solar energy, microelectronics are required product photoelectric transformation efficiency, industry needs
The line thickness of printed pattern is attenuated, at this moment uses existing silk-screen printing technique again, its screen cloth upper warp and woof line institute shape used
Into net knot will have a strong impact on printing slurry even to cause printing to break etc. by, severe patient bad.
The content of the invention
The present invention provides a kind of solar cell preparation technology without net knot printing, to solve to pass through on screen cloth in the prior art
The problem of net knot that parallel is formed has a strong impact on printing slurry, causes printing broken string etc. bad.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
A kind of solar cell preparation technology without net knot printing, wherein positive electrode are used without net knot mode of printing printing,
Specific print steps are as follows：
(1) slurrying：By the raw material of following percentage by weight be placed in 85 DEG C of agitating device stir 10-12 hours be made：
Silver powder 70-75%, Graphene powder 10-15%, glass dust 2-4%, organic carrier 12-15%；
(2) make a plate：Using the integrally formed planar network structure of 3D printing, printing down is reserved needing the position for printing lines
Printing screen plate can be obtained to bit space；
(3) print：Printing screen plate made from step (2) is placed in the travel mechanism moved in parallel relative to bearing ink pad,
It is parallel to each other between plane where plane and bearing ink pad where web plate, and is printed using silver paste made from step (1).
More excellent, organic carrier is by 4,4 '-dichloro diphenyl sulfone, surfactant, thixotropic agent, plasticising described in step (1)
Agent is formed, and surfactant is one or both of organic siliconresin, ATBC, oleic acid, Span 85, and thixotropic agent is
Ethyl cellulose, hydroxyethyl cellulose, castor oil, triglycerin acid fat or tallow acid ester, hard acid fat etc. or comprising hydroxyl or
One or both of high molecular polymer of carboxyl functional group, plasticizer are ATBC or the fourth of phthalic acid two
Ester, 4, the ratio between 4 '-dichloro diphenyl sulfone, surfactant, thixotropic agent, plasticizer is：8:0.2:0.2:1.6.
More excellent, travel mechanism used moves up and down or moved horizontally above bearing ink pad in step (3).
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention uses the integrally formed planar network structure of 3D printing, the net knot no longer formed with latitude and longitude,
The silver paste specially modulated is coordinated to be printed, printing effect is good, solves screen cloth upper warp and woof line institute in the prior art from root
The problem of net knot of formation has a strong impact on printing slurry, causes printing broken string etc. bad；
(2) contain graphene in silver paste of the invention, add conductivity；The dosage of silver powder is reduced simultaneously, is reduced
Production cost；
(3) obtained positive electrode, its plain conductor thinner closeer, battery printing opacity and electrical conduction are printed using the inventive method
