Abstract
A method for manufacturing a solar cell comprises forming a first conductivity-type silicon-based thin-film on a first surface of a substrate; forming a second conductivity-type silicon-based thin-film different from the first conductivity-type silicon-based thin-film, on a second surface of the substrate that is opposite to the first surface of the substrate; forming a first transparent electrode layer on the first conductivity-type silicon-based thin-film; and forming a second transparent electrode layer on the second conductivity-type silicon-based thin-film; forming a first metal seed layer on a first transparent electrode layer; forming a second metal seed layer on a second transparent electrode layer; forming a third metal seed layer on a peripheral edge and on an end-edge of the second conductivity-type silicon-based thin-film; forming a first plating layer on the first metal seed layer and a third plating layer on the third metal seed layer simultaneously by an electroplating method.
