Abstract
A solar cell includes a first photoelectric conversion part, a second photoelectric conversion part, a first electrode, and a second electrode. The first photoelectric conversion part includes a photoelectric conversion layer containing a perovskite compound, a first transport layer, and a second transport layer. The second photoelectric conversion part is arranged below the second transport layer of the first photoelectric conversion part and has a different material or structure from the first photoelectric conversion part. The first electrode is electrically connected to the first photoelectric conversion part on one surface of the first photoelectric conversion part, and the second electrode is electrically connected to the second photoelectric conversion part below the second photoelectric conversion part. The first electrode has a stacking structure of at least two layers, and the second electrode is formed as a single layer.
