Abstract: A solar cell 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.

Abstract: A solar cell module includes: a first substrate; a second substrate positioned so as to face the first substrate; a solar cell disposed on the first substrate so as to be interposed between the first and second substrates; a filler that fills a space between the first and second substrates; and a protective layer disposed on a principal surface of the solar cell that faces the second substrate. The solar cell has a multilayer structure including a photoelectric conversion layer containing a perovskite compound, a hole transport layer, and an electron transport layer. The protective layer contains a polyimide. The protective layer includes a first region that covers the principal surface of the solar cell and a second region in which the principal surface is exposed. A plurality of the first regions or a plurality of the second regions are arranged separately from each other in the protective layer.

Abstract: An ionizing radiation conversion device of the present disclosure includes a first electrode, a second electrode, and an ionizing radiation conversion layer disposed between the first electrode and the second electrode. Here, the first electrode contains a first metal, the second electrode contains at least one selected from the group consisting of second metals and metal oxides, and the ionizing radiation conversion layer contains a perovskite compound. The difference of a value of electron affinity of the ionizing radiation conversion layer minus a value of work function of the first electrode is greater than or equal to 0 eV and less than or equal to 0.4 eV.
