摘要： A composition for solar cell electrodes includes a conductive powder, a glass frit, and an organic vehicle. The glass frit contains about 20 mol % to about 40 mol % of an alkali metal, about 20 mol % to about 30 mol % of zinc (Zn), and about 7 mol % to about 20 mol % of magnesium (Mg) in terms of oxide content.

摘要： A front electrode for a solar cell includes a substrate, a first conductive layer on the substrate, and a second conductive layer on the first conductive layer. The second conductive layer is formed of a composition including silver powder as a first metal powder; and at least one of tin powder, lead powder, and bismuth powder as a second metal powder. The second metal powder is present in an amount of about 0.1 wt % to about 15 wt % based on the total weight of the first conductive layer and the second conductive layer in an unbaked state of the first conductive layer and the second conductive layer.
