Solar cell

A solar cell comprising:

• a semiconductor substrate;
• a conductive area including first and second conductive areas disposed on one surface of the semiconductor substrate;
• a passivation film having opening;
• and
• an electrode including a first electrode connected to the first conductive area and a second electrode connected to the second conductive area,
• wherein the electrode includes an adhesive layer disposed on the semiconductor substrate or the conductive area, an electrode layer disposed on the adhesive layer and including a metal as a main component, and a barrier layer disposed on the electrode layer and including a metal that is different from the metal of the electrode layer as a main component,
• wherein the electrode layer has a thickness greater than a thickness of each of the adhesive layer and the barrier layer,
• wherein a width of the electrode layer is larger than a width of the opening, and
• wherein the barrier layer has a higher melting point than a melting point of the electrode layer.
