Abstract

The invention discloses high-conductivity ferric oxide conductive silver paste. The high-conductivity ferric oxide conductive silver paste is characterized by comprising, by weight, 40-50 parts of silver powder, 1.2-3.4 parts of silver molybdate, 2.1-4.2 parts of ferric oxide, 0.4-0.8 part of sodium selenite, 0.7-1.2 parts of sodium carbonate, 3-5 parts of lauryl alcohol polyoxyethylene ether, 4-7 parts of ethylene glycol dimethacrylate, 0.8-2.1 parts of disodium hydrogen phosphate, 30-40 parts of additives and a proper amount of water. The conductive silver paste is excellent in conductivity, good in adhesive force and complete and compatible in function, the cost of a solar cell of which the positive electrode is prepared through the conductive silver paste is largely lowered, and the conductive silver paste better meets the requirement of large-scale photovoltaic application.

Description

technical field [0001] The invention relates to the field of conductive silver paste, in particular to a highly conductive ferric oxide conductive silver paste and a preparation method thereof. Background technique [0002] Conductive silver paste refers to the silver paste printed on the conductive substrate to make it have the ability to conduct current and eliminate the accumulated static charge. It is generally printed on non-conductive substrates such as plastic, glass, ceramics or cardboard. It is made of conductive Filler, binder, solvent and additive composition. The characteristics that conductive silver paste needs to have are: good conductivity (antistatic property), strong adhesion, good printing adaptability and excellent solvent resistance. However, the existing conductive silver paste on the market has many shortcomings, not only containing lead , cadmium, etc., are toxic, pollute the environment, and when used on conductive substrates, have low adhesion, poo...
