摘要：
Disclosed are lead free glass frit powder for manufacturing a silicon solar cell, its producing method, a metal paste composition containing the same and a silicon solar cell. The lead free glass frit powder for manufacturing a silicon solar cell includes Bi2O3; B2O3; and any one metal oxide selected from the group consisting of ZnO, Al2O3 and BaCO3, or mixtures thereof. The glass frit powder is free of lead, and thus, it is environmental friendly. A front electrode of a solar cell formed using the glass frit powder has low resistance against contact with a substrate and high adhesion to the substrate.
