Patents by Inventor Akiharu Satake

Akiharu Satake has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7884281
    Abstract: A photoelectric transfer material, manufacturing method thereof, photoelectric transfer element and manufacturing method thereof are provided. In an organic photoelectric transfer element of an organic solar cell or other like device, the photoelectric transfer material is composed of a conductive polymer such as MEH-PPV, electronic acceptor such as a fullerene derivative and antenna porphyrin aggregate. The photoelectric transfer material can be made by coating a mixed solution of the conductive polymer, electron acceptor and antenna porphyrin aggregate by spin coating, for example. This photoelectric transfer material and a photoelectric transfer element using the material exhibit high photoelectric transfer efficiency because of small electric resistance and high sunlight usage efficiency, and simultaneously exhibit stability.

  • Patent number: 7192650
    Abstract: A photo-functional molecule element having, on a substrate, a porphyrin polymer containing covalently-fixed porphyrin units, and the method of preparing the same. The photo-functional molecule element may be used as a photoelectric conversion element such as an organic solar cell or a three-dimensional, non-linear organic material.
