Abstract
The solar cell includes an n-type semiconductor layer and a p-type semiconductor layer on a first principal surface of a crystalline silicon substrate. The n-type semiconductor layer is provided so as to extend over a part on a p-type semiconductor layer-formed region provided with the p-type semiconductor layer, and a p-type semiconductor layer non-formed-region where the p-type semiconductor layer is not provided. In a region where the n-type semiconductor layer is provided on the p-type semiconductor layer, a protecting layer is between the p-type semiconductor layer and the n-type semiconductor layer. The protecting layer includes: an underlying protecting layer that is in contact with the p-type semiconductor layer; and an insulating layer that is on the underlying protecting layer. The underlying protecting layer includes an intrinsic silicon-based layer or an n-type silicon-based layer.
