Patent number: 10673002Abstract: Organic photoelectric conversion element has a first electrode, a photoelectric conversion layer, and a second electrode. The photoelectric conversion layer has a first organic layer that contains a first organic semiconductor containing principally a p-type organic semiconductor, a second organic layer that contains a second organic semiconductor containing principally an n-type organic semiconductor, and an intermediate layer that contains the first organic semiconductor and the second organic semiconductor. The second organic layer is disposed at a side of the second electrode relative to the first organic layer. The intermediate layer is between the first organic layer and the second organic layer and reaches each of these layers. The thickness of the second organic layer is greater than the sum of the thicknesses of the first organic layer and intermediate layer.Type: GrantFiled: April 18, 2017Date of Patent: June 2, 2020Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Shigeo Hara, Wataru Akahori, Takahiko Yamanaka, Tadataka Edamura
