Abstract: An i-type layer is formed on a side of one surface of a crystalline semiconductor substrate. An n-type layer or a p-type layer is formed on the i-type layer and includes a conductive impurity. A TCO is formed on the n-type layer or the p-type layer. A density in a proximate portion of the n-type layer or the p-type layer closer to the TCO than a remote portion of the n-type layer or the p-type layer is smaller than a density in the remote portion.

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.
