Abstract: Methods for manufacturing a solar cell that includes a first substrate, a first electrode layer, a first electron transport layer, a first photoelectric conversion layer, a first hole transport layer, a second electrode layer, a third electrode layer, a second electron transport layer, a second photoelectric conversion layer, a second hole transport layer, a fourth electrode layer, and a second substrate that are disposed in the order stated. The first photoelectric conversion layer includes a first perovskite compound, and the second photoelectric conversion layer includes a second perovskite compound. The first perovskite compound has a bandgap greater than a bandgap of the second perovskite compound.
