Abstract: Discussed is a solar cell including a semiconductor substrate, a conductive region disposed in the semiconductor substrate or over the semiconductor substrate, and an electrode electrically connected to the conductive region. The electrode includes a first electrode part and a second electrode part disposed over the first electrode part. The second electrode part includes a particle connection layer formed by connecting a plurality of particles including a first metal and a cover layer including a second metal different from the first metal and covering at least the outside surface of the particle connection layer.
