Abstract
A conductive paste for forming a solar cell electrode, including: a conductive powder comprising 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.
Claims7
A method for manufacturing a solar cell device, comprising the steps of providing a semiconductor substrate exhibiting one conductivity type;
- forming a region exhibiting a conductive type opposite to the one conductivity type of the semiconductor substrate on a surface of the semiconductor substrate from a light-receiving surface thereof;
- forming an antireflective film on the region;
- and forming a front electrode on the antireflective film,
- wherein the front electrode is formed by applying a conductive paste including a conductive powder comprising silver as a main component, glass frit and an organic vehicle onto the antireflective film;
- and firing the applied conductive paste, the glass frit containing tellurium glass frit having tellurium oxide as a network-forming component.
