ABSTRACT:
The organic photoelectric conversion element according to the invention has enhanced the light-absorbing property by incorporating two or more kinds of electron donating organic materials4aand4bin the photoelectric conversion region14. With such measure, it has become possible to efficiently absorb the incident light and enhance the photoelectric conversion characteristic. In addition, a light-to-light conversion material7is incorporated in the photoelectric conversion region, too. With this measure, even the light of such a wavelength that an electron donating organic material cannot inherently absorb comes to be absorbed since the light-to-light conversion material7converts the wavelength, thus enabling the light to be utilized for carrier generation. Accordingly, an organic photoelectric conversion element with a high conversion efficiency can be obtained.
