Abstract: The present invention relates to a novel cathode buffer layer material, and an organic or organic/inorganic hybrid photoelectric device comprising same, and, if a novel compound of the present invention is applied to a cathode buffer layer of an organic photoelectric device such as organic solar cells, organic photodiode, colloidal quantum dot solar cell, and perovskite solar cell, a surface property of an electron transfer layer is improved via a high dipole moment of the novel compound, an electron can be easily extracted from a photoactive layer to a cathode electrode, and series resistance and leakage current can be reduced, thereby having a useful industrial effect, as performance of the organic or organic/inorganic hybrid photoelectric device being manufactured, such as an organic solar cell, organic photodiode, colloidal quantum dot solar cell, and perovskite solar cell, can be significantly improved.
