Problems solved by technology

However, PCBM is extremely expensive, looking for cheaper n-type semiconductor materials
[0004] As one of the alternative material candidates for PCBM, the use of metal oxide nanoparticles that can function as n-type semiconductor materials has also been studied, but the photoelectric conversion efficiency tends to decrease compared with the case of using PCBM

Embodiment

[0103]

[0104] [Preparation of Ti-containing compound slurry]

[0105] Titanium (IV) sulfate solution (manufactured by Kanto Chemical Co., Ltd., diluted to 12% by mass of titanium sulfate) and NH 3 Water (manufactured by Kanto Chemical Co., Ltd., diluted to 4% by mass) was neutralized, and the obtained precipitate was filtered and washed to obtain a Ti-containing compound. After adjusting the pH to 10.5 in NH 3 The Ti-containing compound was dispersed in water at a concentration of 1% by mass to obtain a Ti-containing compound slurry.

[0106] [Preparation of carbon-coated titanium oxide nanoparticles]

[0107] As the metal oxide raw material, the above-mentioned Ti-containing compound slurry was used. Glucose (manufactured by Wako Pure Chemical Industries, Ltd.) was used as a raw material of the carbon material. 12 g of glucose was added to 1200 mL of the Ti-containing compound slurry, the mixture was placed in a Hastelloy pressure reactor, and treated in a supercritic...

Abstract

Disclosed is an organic photoelectric conversion element (10) provided with an active layer (40) which contains an organic compound and which is disposed between the electrodes of an electrode pair comprising a first electrode (32) and a second electrode (34). Because said active layer contains metal oxide nanoparticles with a carbon material adhered on the surface, the organic photoelectric conversion element (10) can be produced with low-cost materials.

Description

technical field [0001] The present invention relates to an organic photoelectric conversion element and a device carrying the organic photoelectric conversion element. Background technique [0002] Research and practical use of photoelectric conversion elements constituting solar cells that convert light into electric power, image sensors that convert images into electrical signals, and the like are currently underway. In a photoelectric conversion element that is being put into practical use today, an inorganic semiconductor material is generally used for an active layer having photoelectric conversion activity. In view of this, photoelectric conversion elements (hereinafter referred to as organic photoelectric conversion elements) in which organic compound materials are used in the active layer having photoelectric conversion activity are attracting attention from the viewpoint of further thinning and increasing the area of ​​the element. [0003] Currently, fullerene der...
