Abstract
A conductive paste for forming a solar cell electrode, including: a conductive powder containing silver as a main component; glass frit; and an organic vehicle, wherein the glass frit contains tellurium glass frit having tellurium oxide as a network-forming component. The conductive paste of the present invention makes it possible to form a solar cell electrode having a low dependence on firing temperature without causing problems due to fire-through into the substrate, and to thereby obtain a solar cell having good solar cell characteristics.
