Abstract

The invention relates to the technical field of silver paste, in particular to a conductive silver paste for a photovoltaic cell. The conductive silver paste for the photovoltaic cell comprises the components of, by weight, 1-5 parts of body glass, 0.1-0.5 part of auxiliary glass, 35-60 parts of organic binding agents, 14-19 parts of thermoplastic polyimide resin and 50-70 parts of conductive phase. The conductive silver paste for the photovoltaic cell is unique in design, reasonable in composition and convenient in preparation, has excellent conductivity and good adhesion with a base material, the adhesion, workability, hardness and diffusivity of a coating are ensured while improving the conductive and mechanical properties of the coating, and small environmental pollution is achieved.

Description

technical field [0001] The invention relates to a silver paste, in particular to a conductive silver paste for a photovoltaic cell. Background technique [0002] As a functional printing material, conductive paste has been widely used in electronic information products due to its good physical properties. With the development of electronic products to be lighter, thinner, more functional and more environmentally friendly, its Performance also puts forward higher requirements. Among them, the low-temperature halogen-free conductive silver paste is widely used in membrane switches, capacitive electrodes, touch screens, etc. because of its excellent electrical conductivity, thermal conductivity, and practicability. Low-temperature conductive silver paste is a uniform paste made by stirring and dispersing conductive silver powder as a conductive filler with high polymer resin, solvent, curing agent, and additives. After the conductive silver paste is coated on the substrate, i...
