Abstract
A bifacial solar cell is discussed. The bifacial solar cell includes a substrate, a p-type doped region positioned at a first surface of the substrate, a P-type electrode part electrically connected to the p-type doped region, an n-type doped region positioned at a second surface of the substrate, and an N-type electrode part electrically connected to the n-type doped region. The P-type electrode part is formed of a first inorganic solid powder including a first powder, which contains silver (Ag) and has an average diameter of about 0.2 μm to 1 μm, and a second powder, which contains a group III element and has an average diameter of about 1 μm to 5 μm. The N-type electrode part is formed of a second inorganic solid powder including only the first powder.
