Abstract
Provided is a solar cell having improved photoelectric conversion efficiency. The solar cell () contains: a substrate () comprising a semiconductor material having one type of conductivity; a first semiconductor layer () having the one type of conductivity; and a second semiconductor layer () having the one type of conductivity. The first semiconductor layer () is arranged on one main surface of the substrate (). The second semiconductor layer () is arranged on the other main surface of the substrate (). The solar cell () is configured such that the strength of the electric field formed by the second semiconductor layer () is greater than the strength of the electric field formed by the first semiconductor layer ().
