COMPOSITION FOR FORMING SOLAR CELL ELECTRODE AND ELECTRODE PRODUCED FROM SAME |
| 摘要 |
A composition for solar cell electrodes and electrodes fabricated using the same. The composition includes silver powder; fumed silica; a glass frit; and an organic vehicle. The composition has improved contact efficiency between electrodes and a silicon wafer by introducing specific fumed silica. Solar cell electrodes fabricated using the composition exhibit minimized serial resistance, thereby providing excellent fill factor and conversion efficiency. |
