摘要： The present invention relates to a conductive paste for a solar cell electrode, including a metal powder, a glass frit, an organic binder, a silicone-based additive and a solvent, wherein the silicone-based additive includes trimethylsiloxy-terminated polydimethylsiloxane, whereby an electrode formed using the conductive paste can be improved in aspect ratio, that is, line width and line height, thus increasing conductivity, and a solar cell having high power generation efficiency can be provided by enlarging the light-receiving surface through decreasing the line width of the electrode.
