Abstract

A solar cell including a p-electrode, an n-electrode, a p-type light-absorbing layer on the p-electrode including a cuprous oxide compound as a main component, and an n-type layer between the p-type light-absorbing layer and the n-electrode. The p-type light-absorbing layer incudes a first element selected from the group consisting of Zn, Mg, Cd, and Ca on the n-type layer side. The p-type light-absorbing layer is in direct contact with the n-type layer. A concentration of the first element in a region from an interface between the p-type light-absorbing layer and the n-type layer to a depth of 50 [nm] or less toward the p-electrode side is 90 [atomic%] or more and 100 [atomic%] or less of a concentration of the first element included in the p-type light-absorbing layer.
