Embodiment 1

[0067] Adopt the following method to prepare strontium ruthenate nanoparticle composite silver paste:

[0068] 1. Preparation of silver / strontium ruthenate complex: in the silver / strontium ruthenate complex, the content of strontium ruthenate is 0.2w%, and the balance is silver powder. The specific preparation method is as follows:

[0069] 1) Prepare 100mL of 0.1mol / L silver nitrate solution (A solution);

[0070] 2.) Prepare 100 mL of reducing solution (solution B), 1.056 g of ascorbic acid, 0.68 g of polyvinylpyrrolidone (PVP), 0.68 g of polyvinylpyrrolidone (PVP), deionized water as the solvent, and adjust the pH value of the reducing solution to 4 with 6% ammonia water;

[0071] 3) Add 0.2g of strontium ruthenate to solution B, stir for 15min, and sonicate for 15min;

[0072] 4) Keep solution B under stirring and ultrasonic, and add solution A to it co-currently and dropwise at a speed of 1ml / min;

[0073] 5) The solution after the reaction was completed was filtered an...

Embodiment 2～4

[0087] The silver / strontium ruthenate composite, the silver-coated glass powder, the organic carrier and the inorganic additives prepared in Example 1 were prepared according to the required proportions, and the proportions are shown in Table 1. Fully dispersing and mixing by a three-roll mill, performing a viscosity test, and adjusting the viscosity to obtain a strontium ruthenate nanoparticle composite silver paste with uniform dispersion and moderate viscosity.

[0088] The obtained strontium ruthenate nanoparticle composite silver paste has no hard lumps after being stirred, and is in a uniform state, and has good soldering performance, and its performance test is shown in Table 2.

[0089] Table 1

[0090]

Embodiment 5

[0092] Using the method of Example 1, the only difference is that in the silver / strontium ruthenate composite, the content of strontium ruthenate is 0.02w%, and the balance is silver powder. The prepared strontium ruthenate nanoparticle composite silver paste has no hard lumps after stirring, and is in a uniform state, and has good soldering performance. The performance test is shown in Table 2.

Abstract

The invention relates to strontium ruthenate nanoparticle composite silver paste and a preparation method thereof, belongs to the technical field of conductive silver paste, and aims at solving the technical problem of providing the strontium ruthenate nanoparticle composite silver paste. The strontium ruthenate nanoparticle composite silver paste is prepared from the following components in parts by weight: 72-84 parts of silver/strontium ruthenate complex, 3-15 parts of silver-coated glass powder, 10-33 parts of organic carriers and 0-3 parts of inorganic additives. Compared with existing conductive silver paste, the strontium ruthenate nanoparticle composite silver paste provided by the invention has better electrical property and better stability.

Description

technical field [0001] The invention relates to strontium ruthenate nanoparticle composite silver paste and a preparation method thereof, belonging to the technical field of conductive silver paste. Background technique [0002] Facing the increasingly severe energy situation and the deterioration of the ecological environment, changing the existing energy structure and developing sustainable green energy has become a topic of great concern to all countries in the world. Solar energy has the advantages of abundant resources, clean and harmless, and reliable, which makes it inevitable that direct application of solar energy will become a way for human beings to use energy. One of the main ways to obtain clean energy from the sun is the solar cell, which has been invented for half a century and has received high attention and rapid development in contemporary times. [0003] The solar cell technology is relatively mature at present. Conductive silver paste, as the key materia...
