摘要： Proposed is a conductive paste for a solar cell electrode. The conductive paste includes a metal powder, a glass frit, an organic vehicle, a silicone oil and an additive. The use of the silicone oil included in the conductive paste resolves the problem of phase separation and significantly improves slip properties of the conductive paste, thereby enabling the implementation of fine line widths.
