A composition for solar cell electrodes, the composition comprising:
- a conductive powder;
- a glass frit;
- and
- an organic vehicle, wherein the conductive powder includes a first silver powder having a cross-sectional particle porosity of 0.1% to 4%;
- wherein the conductive powder further includes a second silver powder that is different from the first silver powder;
- and
- wherein:
- the first silver powder is present in an amount of about 30 wt % to about 95 wt %, and the second silver powder is present in an amount of about 5 wt % to about 70 wt %, all wt % being based on a total weight of the conductive powder.
