The present invention relates to a novel cathode buffer layer material and an organic photoelectric device including the same. When the novel compound of the present invention is applied to a cathode buffer layer of an organic photoelectric device, for example, an organic solar cell or an organic photodiode, there is an effect in which the surface characteristics of an electron transport layer are improved through the high dipole moment of the novel compound to thereby facilitate electron extraction from a photoactive layer to a cathode electrode and to reduce series resistance and leakage current, and accordingly, the performance of an organic optoelectronic device (organic solar cell, organic photodiode, etc.) to be manufactured can be remarkably improved, which is industrially advantageous.
本发明涉及一种新型阴极缓冲层材料以及包括该材料的有机光电器件。当本发明的新化合物应用于有机光电器件的阴极缓冲层时,例如有机太阳能电池或有机光电二极管,通过新化合物的高偶极矩改善了电子传输层的表面特性,从而促进了从光活性层到阴极电极的电子提取,减少了串联电阻和泄漏电流,因此,制造的有机光电器件(有机太阳能电池、有机光电二极管等)的性能可以得到显著改善,这在工业上具有优势。
