Abstract

The invention provides a conductive paste for high-performance solar cell and a preparation method thereof. The conductive paste is prepared by using the following raw materials, by weight: 60 to 80 parts of lauric acid modified conductive nano powder, 6 to 12 parts of glass powder, 5 to 14 parts of long-oil alkyd resin, 7 to 15 parts of polystyrene resin, 3 to 6 parts of carboxy nitrile rubber, 5to 9 parts of propylene glycol methyl ether acetate, 3 to 8 parts of rosin maleate, 6 to 10 parts of 2-hydroxyethyl methacrylate, 2 to 5 parts of propylene glycol n-butyl ether, 1 to 3 parts of trioctyl trimellitate, 2 to 6 parts of zinc naphthenate, 1 to 4 parts of lubricants, 1-5 parts of film formation auxiliary agents and 1 to 3 parts of thickeners. According to the invention, the prepared conductive paste matches the substrate well by adjusting contents of inorganic components and organic components; and the conductive paste has excellent conductive performance, contact performance, andconnection performance. Therefore, when the conductive paste is used for prepring the solar cell electrode, the power generation efficiency of the solar cell is improved substantially.

Description

technical field [0001] The invention relates to a conductive paste, in particular to a conductive paste for high-performance solar cells and a preparation method thereof. Background technique [0002] As a renewable and clean energy, solar energy is inexhaustible and inexhaustible, and almost no environmental pollution is generated during use. After 40 years of development, more research is now focused on how to apply solar cells, solar cars, and solar buildings to people's real life, so as to reduce the dependence on traditional energy sources. With the continuous deepening of solar cell research and development, solar cells have basically entered the stage of industrial application. At present, the solar cell materials on the market are mainly silicon-based solar cells, including crystalline silicon, crystalline silicon and polycrystalline silicon thin films, solar cells, and silicon-based thin-film solar cells. Batteries, etc., and some are non-silicon solar cells, such ...
