Abstract
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.
