Abstract: The electrode catalyst ink includes a catalyst including a layered double hydroxide, an organic polymer, and a solvent. The solvent includes a first solvent, a second solvent, and a third solvent. The third solvent has a boiling point higher than a boiling point of the first solvent and higher than a boiling point of the second solvent. The Hansen solubility parameter distance Ra1 [MPa1/2] between the third solvent and the catalyst and the Hansen solubility parameter distance Ra2 [MPa1/2] between the third solvent and the organic polymer satisfy a relationship of 2.08Ra1−16.0≤Ra2≤2.08Ra1−13.5.

Abstract: A photosensor includes a first electrode, a second electrode that opposes the first electrode, and a photoelectric conversion layer that is disposed between the first electrode and the second electrode and converts incident light into electric charges. At least one electrode selected from the group consisting of the first electrode and the second electrode is light-transmissive. The photoelectric conversion layer contains a perovskite compound. The fluorescence spectrum of the perovskite compound has a first peak at a first wavelength and a second peak at a second wavelength that is longer than the first wavelength. The photoelectric conversion layer is in ohmic contact with each of the first electrode and the second electrode.
