Abstract

Provided is a solar cell including a pair of electrodes, and a photoelectric conversion layer of chalcopyrite structure sandwiched between the pair of electrodes. At least one of the pair of electrodes, adapted to serve as a transparent electrode, has a nitrogen-containing layer composed with the use of an organic compound containing a nitrogen atom, and an electrode layer containing a metal of the Group 11 of the periodic table, which is provided to be laminated on the nitrogen-containing layer, thereby improving the photoelectric conversion efficiency.
