Abstract
The invention relates to the technical field of conductive slurry and especially relates to solar battery front-surface electrode conductive slurry with low solvent volatility and a preparation method thereof. The solar battery front-surface electrode conductive slurry comprises the following components: 80-90% of metal silver powder, 1-10% of glass powder and 4-15% of an organic carrier, wherein a solvent included in the organic carrier has quite low vapor pressure. The organic carrier is composed of the following components: 60-85% of the solvent, 5-35% of a resin, and 1-10% of other auxiliary agents. The organic carrier is prepared by use of the following method: each component of the organic carrier is pre-mixed in a container, then is stirred in an oil bath at a temperature of 85 DEG C for 12 hours, is insulated for 3 hours and then is cooled such that the organic carrier can be obtained. According to the invention, an ionic liquid is taken as the slurry for manufacturing the solvent, the printing performance can be well maintained in a long-time application process, and the problems of slurry drying, printing difficulty and the like due to volatilization of the solvent are not caused.
Description
Technical field
The present invention relates to electrocondution slurry technical field, especially a kind of low solvent volatility front electrode of solar battery are used
Electrocondution slurry and preparation method.
Background technology
In solar cell making process, the industrial method one of Ohm contact electrode is formed on its semiconductor surface
As be silk screen printing, electrocondution slurry is coated in into silicon chip surface by way of silk screen printing, through drying, sintering be allowed to metal
Change forms electrode.
The electrocondution slurry of silk screen printing has conductive phase, glass phase and organic carrier phase composition.Conductive phase is mainly metal
Argentum powder, as the conductive materials of electrode.Glass is made up of metal and nonmetallic oxide, and liquid is produced in sintering process
Phase, burns the antireflection film such as silicon nitride and provides cohering for silicon chip and electrode.Organic carrier plays moistening, dispersion powder granule
Effect, and provide slurry good printing performance.Solvent in organic carrier play dissolving cellulose, polyamide it is cured and its
The effect of its various resin.Partial organic solvent also has change slurry plasticity simultaneously, or changes pulp surface activity, or
Person changes the effect such as surface tension, and these effects contribute to slurry and form the conductive electrode with high depth ratio.Organic carrier exists
Gradually volatilize from slurry in drying sintering process after printing, formed on silicon substrate surface and coordinated packet by conductive phase and glass
Into conductive electrode.
