Problems solved by technology

With the narrowing of the line width and the increase of the number of meshes, the probability of screen blocking, disconnection and virtual printing during the printing process is relatively high. If the paste cannot be printed on the surface of the cell quickly and completely, it will directly Affect the production of subsequent components and even cause the manufacturer to stop production

Abstract

The invention discloses an organic carrier for a solar electronic slurry and an electronic slurry containing the same. The organic carrier comprises the following components, by weight: 2 to 30% of apolymer carrier, 20 to 50 of a solvent, 10 to 50% of a screening agent, 5 to 10% of a wetting agent, 5 to 20% of a solid formulation blending agent, 5 to 20% of an anti-oxygen agent, and 5 to 10% of an anti-skinning agent. The polymer carrier is prepared by a polymerization reaction between an organic alkene substance and polyhydric alcohols. The electronic slurry is composed of 10 to 50% of an organic vehicle, 50 to 90% of silver powder, and 1.5 to 3.5% of glass powder. Besides, the preparation process of the electronic slurry comprises steps of organic weighing, ultrasonic dispersion, low-speed stirring, powder weighing, low-speed stirring, grinding, and vacuum stirring. According to the invention, the electronic slurry prepared by the prepared organic carrier has the good screening performance; the printing line mode is well structured; and the depth-width ratio is high. With the obtained electronic slurry, phenomena of solvent precipitation, blockage, and virtual printing during silk-screen printing can be avoided.

Description

technical field [0001] The invention relates to a preparation method of an organic carrier of solar paste and a solar electronic paste. Specifically, it relates to preparing an organic carrier of solar electronic paste by means of a polymerization reaction between organic olefin and polyol, and using the carrier to produce solar electronic paste through a certain process, which belongs to the field of solar photovoltaic. Background technique [0002] A solar cell is an energy converter that directly converts light energy into electrical energy based on the photovoltaic effect generated by receiving sunlight on a semiconductor P-N junction. Such as Figure 4 As shown, the photoelectric conversion process can be summarized as follows: when sunlight irradiates the solar cell, part of it is reflected by the surface of the solar cell, another part is absorbed by the solar cell, and a small amount passes through the solar cell. Among the photons absorbed by the solar cell, those ...
