Abstract:
1. A solar cell comprising: a p-type semiconductor layer containing a group Ib element, a group IIIb element, and a group VIb element; and an n-type semiconductor layer containing a group Ib element, a group IIIb element, a group VIb element, and Zn and formed on the p-type semiconductor layer, wherein a content of the group Ib element in the n-type semiconductor layer is from 15 to 21 at. % to a total number of atoms of the group Ib element, the group IIIb element, the group VIb element, and Zn in the n-type semiconductor layer, wherein a content of Zn in the n-type semiconductor layer is from 0.005 to 1.0 at. % to the total number of atoms of the group Ib element, the group IIIb element, the group VIb element, and Zn in the n-type semiconductor layer, and wherein Zn is uniformly dispersed in the n-type semiconductor layer.
