A solar cell comprising a first electrode, a photoelectric conversion layer, an intermediate layer, a hole transport layer, and a second electrode in this order, wherein,
- the hole transport layer includes a hole transport material and an oxidant,
- the photoelectric conversion layer includes a perovskite compound containing iodine, and
- the intermediate layer includes at least one selected from the group consisting of bromide, chloride, and fluoride.
A solar cell comprising a first electrode, a photoelectric conversion layer, an intermediate layer, a hole transport layer, and a second electrode in this order, wherein,
- the hole transport layer includes a hole transport material and an oxidant,
- the photoelectric conversion layer includes a perovskite compound containing iodine, and
- an absolute value of a redox potential for neutralization of the cationized hole transport material is larger than an absolute value of a redox potential for neutralization of anions generated when the intermediate layer is ionized.
