Abstract
A solar cell of an embodiment includes: a transparent substrate; a p-electrode on the substrate, the p-electrode including a first p-electrode containing an Sn-based metal oxide, a second p-electrode having an opening and consisting of a wiring containing a metal or graphene, and a third p-electrode containing an In-based metal oxide; a p-type light absorbing layer in direct contact with a surface of the first p-electrode on a side opposite to the second p-electrode side; an n-type layer provided on the p-type light absorbing layer; and an n-electrode provided on the n-type layer. The third p-electrode is provided to be present between the first p-electrode and the second p-electrode and to be in direct contact with an upper surface of the second p-electrode. An entire side surface of the second p-electrode is in direct contact with the first p-electrode.
