Abstract

The invention discloses electrical conductive slurry comprising acetyl triethyl citrate. The electrical conductive slurry is mainly made of, by weight, 70-75 of material A, 22-25 of material B, 0.3-0.6 of dimethyl azelate, 1-2 of silane coupling agent carbonate hardness (KH) 580, 1-2 of castor oil, and 0.3-0.5 of organic silicone oil. The electrical conductive slurry does not contain plumbum, completely meets environment-friendly requirements, is applied to production of solar cells, can form strong adhesive force on the surfaces of the solar cells, enables photovoltaic conversion efficiency of the cells to be high, meanwhile, utilizes silver powder, aluminum powder and copper powder which are different in grain diameter, increases contacting areas among grains, and therefore improves conductivity of silver slurry.

Description

technical field [0001] The invention relates to the field of electronic fine chemicals, in particular to a conductive paste containing acetyl triethyl citrate. Background technique [0002] Conductive paste is the key material for packaging, electrodes and interconnection of electronic components, mainly including two categories: burn-in type conductive paste and curable conductive adhesive (conductive ink). [0003] Firing type conductive paste is mainly used in industries such as solar cells and used as electrodes after sintering, and curable conductive ink is widely used in printed circuit and electronic packaging industries. [0004] According to the different fillers, the conductive paste can be divided into carbon paste (graphite conductor), metal paste (gold powder, silver powder, copper powder, silver-copper alloy), and modified ceramic paste. [0005] In terms of performance comparison, the conductivity of the precious metal filler is the best, followed by the carb...
