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.

摘要： Disclosed herein is a composition for solar cell electrodes. The composition includes a conductive powder, a glass frit, and an organic vehicle, wherein the glass frit is a bismuth oxide-tellurium oxide-zinc oxide-lithium oxide-based glass frit comprising: 5 wt % to 20 wt % of bismuth oxide; 55 wt % to 80 wt % of tellurium oxide; 0.1 wt % to 15 wt % of zinc oxide; and 0.1 wt % to 10 wt % of lithium oxide. Solar cell electrodes formed of the composition have low serial resistance (Rs) and high open voltage (Voc), thus providing high conversion efficiency and good adhesive strength with respect to a ribbon.
