Abstract
Organic semiconductor layers comprise between a first electrode and a photoelectric converting layer a light extraction improving layer that contains at least silver or gold in part as a component, partially reflects light, and has transparency. The light extraction improving layer is in contact with or is inserted into a functional layer containing, for example, an organic semiconductor material, an oxide, a fluoride, or an inorganic compound having strong acceptor properties or strong donor properties with an ionization potential of 5.5 eV or higher, within the organic semiconductor layers.
Claims2
A panel comprising:
- a first electrode;
- a second electrode;
- an organic layer;
- and
- a light extraction improving layer that includes an oxide between said organic layer and said first electrode, said light extraction improving layer comprising a discontinuous portion.
