Abstract
A method of manufacturing a finger electrode for a solar cell includes printing a conductive paste on a front surface of a substrate using a printing mask having an opening rate of 65% or more, and baking the printed conductive paste. The conductive paste may include a conductive powder, a glass frit, and an organic vehicle, and the conductive powder may include a first conductive powder having a particle diameter (D50) of about 0.1 μm to about 1.5 μm and a second conductive powder having a particle diameter (D50) of greater than 1.5 μm to about 5 μm, and the conductive powder as a whole has a particle diameter (D10) of about 0.5 μm or less.
