Examples of other organic materials included in the photoelectric conversion layer 24 include fullerene or a fullerene derivative. Fullerene or a fullerene derivative corresponds to a specific example of a “second organic semiconductor material” of the present disclosure.
Furthermore, the photoelectric conversion layer 24 may include, for example, an organic semiconductor material that absorbs any of wavelengths from 400 nm to 700 nm both inclusive. Examples of such a material include a coumarin derivative, a perylene derivative, a porphyrin derivative, a merocyanine derivative, an anthraquinone derivative, and the like. The organic semiconductor material described above corresponds to a specific example of a “third organic semiconductor material” of the present disclosure.
A combination of the organic materials described above function as a p-type semiconductor or an n-type semiconductor depending on the combination.
