Abstract: A solar cell includes: a silicon substrate including a texture structure in a first principal surface; and a first non-crystalline silicon layer formed on the first principal surface of the silicon substrate and including recesses and protrusions reflecting the texture structure. At a valley portion in the recesses and protrusions, the first non-crystalline silicon layer includes, in the stated order: a first epitaxial layer including a crystalline region epitaxially grown on the silicon substrate; a first amorphous layer which is a non-crystalline silicon layer; and a second amorphous layer which is a non-crystalline silicon layer. The density of the first amorphous layer is less than the density of the second amorphous layer.
