Abstract
The present invention discloses a conductive paste for solar cell, including the following composition: (a) a silver powder; (b) a filler which can be coated with a conductor; (c) a glass frit; and further (d) a dispersing agent, an organic vehicle, and at least one additive. The filler, especially conductor coated, is used to replace part of silver powder as an ingredient of the conductive paste and thus reduces manufacturing cost without conductivity diminishing. This conductive paste can be utilized to form the front-side electrode of the substrate for solar cell.
