- NOVEL CATHODE BUFFER LAYER MATERIAL AND ORGANIC PHOTOELECTRIC DEVICE INCLUDING SAME
-
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.
