Photoelectric transfer material, manufacturing method thereof, photoelectric transfer element and manufacturing method thereof

摘要

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.
