Solar Cell

Abstract

A solar cell includes a photoelectric conversion layer, a first electrode on one surface of the photoelectric conversion layer, a second electrode on other surface of the photoelectric conversion layer, and a third electrode on the other surface of the photoelectric conversion layer. The third electrode is substantially rectangular with its corners rounded off in the in-plane direction of the photoelectric conversion layer, and overlaps the second electrode at the periphery thereof.
