Abstract
A crystalline silicon-based solar cell includes, in the following order, a crystalline silicon substrate having a first principal surface, a non-single-crystalline silicon-based thin-film, and a transparent electroconductive layer. The non-single-crystalline silicon-based thin-film and the transparent electroconductive layer are disposed on the first principal surface. The non-single-crystalline silicon-based thin-film comprises, in the following order from the first principal surface, an intrinsic silicon-based thin-film and a conductive silicon-based thin-film. The first principal surface has a plurality of pyramidal projections, each having a top portion, a middle portion, and a bottom portion. A thickness of the non-single-crystalline silicon-based thin-film disposed on the top portions is smaller than a thickness of the non-single-crystalline silicon-based thin-film disposed on the middle portions.
