Abstract: An embodiment of a solar cell is provided comprising a silicon substrate, on a first surface of which a texture structure including mountain portions and valley portions is formed, and an amorphous silicon layer provided on the first surface of the silicon substrate. The texture structure, in a cross section passing through the mountain portions and the valley portions, includes pairs of slant portions, each pair slanting to extend from a pair of neighboring ones of the mountain portions toward the valley portion therebetween while coming closer to each other. The valley portion located between the slant portions is in a round shape with a radius of curvature of 150 nm or smaller. The amorphous silicon layer includes an epitaxial growth area grown from the valley portion, the epitaxial growth area on the valley portion is thicker than that on a region other than the valley portion.
