    • 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 materials 4a and 4b in the photoelectric conversion region 14. 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 material 7 is 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 material 7 converts 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.
    • 根据本发明的有机光电转换元件通过在光电转换区域14中引入两种或更多种给电子有机材料4a和4b来增强光吸收性能。通过这种措施,已经有可能有效地吸收事件 光和增强光电转换特性。 此外,光电转换材料7也并入光电转换区域中。 通过该测量,由于光 - 光转换材料7转换波长,所以即使由供电子有机材料不能固有地吸收的这种波长的光也被吸收,因此能够将光用于载体产生。 因此,可以获得具有高转换效率的有机光电转换元件。
