Abstract
A conductive paste and a solar cell. The conductive paste includes a conductive powder, a first glass frit, and a second glass frit. The first glass frit includes at least one of lead-containing glass and bismuth-containing glass. A glass transition temperature of the second glass frit is greater than 600° C. In the conductive paste, a weight percentage of the first glass frit ranges from 0.5% to 5%, and a weight percentage of the second glass frit ranges from 0.5% to 10%.
