Low-temperature cured conductive silver paste used for solar cell

The invention relates to a low-temperature cured conductive silver paste used for a solar cell. The paste comprises, by weight, 86-92wt% of a nanometer silver powder, 0.5-2wt% of a nanometer aluminum powder, 2-4wt% of a thermoplastic resin, 0.1-2wt% of an additive and 1-10wt% of a solvent. By using the above technical scheme, the obtained low-temperature cured conductive silver paste used for the solar cell possesses low temperature curing and curing time is short; a depth-width ratio of an electrode of the made solar cell is large, and a filling factor of the solar cell is increased so that conversion efficiency of the solar cell is improved.
