There is presented a solar cell comprising a semiconductor substrate of one conductivity-type, a layer of the opposite conductivity-type provided on a surface side of the semiconductor substrate, a surface electrode formed thereon, and a backside electrode formed on a backside of the semiconductor substrate, wherein the semiconductor substrate is formed with protrusions and recesses on the surface side thereof, and spaces that are filled with a glass component of an electrode material of the surface electrode are present in bottom portions of the recesses. This arrangement has eliminated a conventional problem in that silver in the electrode material gets into the bottom portions of the recesses and causes defects to be generated in the recesses due to stress generated during forming of the electrode.
