Bifacial solar cell |
摘要 |
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. |

1. A bifacial solar cell comprising:
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, wherein 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 aluminum (Al) and has an average diameter of about 1 μm to 5 μm, and wherein the N-type electrode part is formed of a second inorganic solid powder including only the first powder. |
