A solar cell according to an embodiment includes a p-electrode, an n-electrode, a p-type light-absorbing layer provided on the p-electrode and being mainly composed of a cuprous oxide compound, an n-type layer disposed between the p-type light-absorbing layer and the n-electrode, and a compound of first metal provided between the p-type light-absorbing layer and the n-type layer. Coverage of the compound of the first metal covering the p-type light absorption layer is 10% or more and less than 100%. The first metal is one or more elements selected from the group consisting of Al, Hf, Zr, and B. The cuprous oxide compound is in direct contact with the compound of the first metal and the n-type layer.
