Abstract
A solar cell includes a conductive area including first and second conductive areas on one surface of a 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, the electrode including an adhesive layer on the semiconductor substrate or the conductive area, an electrode layer on the adhesive layer and including a metal, and a barrier layer disposed on the electrode layer and including a metal that is different from the metal of the electrode layer, the electrode layer having a thickness greater than a thickness of each of the adhesive layer and the barrier layer, a width of the electrode layer being larger than a width of the opening, and the barrier layer having a higher melting point than a melting point of the electrode layer.
