Abstract: The present invention relates to an organic-inorganic hybrid solar cell including an organic surface modifier and a fabricating method thereof, wherein the organic-inorganic solar cell includes: a first substrate; a first electrode formed on the first substrate; a semiconductor layer formed on the first electrode and introducing concurrently dye and the organic surface modifier on its surface; a second substrate; and a second electrode formed on the second substrate while facing the first electrode. The present invention introduces the organic surface modifier on a surface of a titanium dioxide semiconductor compound due to a configuration including electrolyte introduced between the first electrode and the second electrode and blocks a lost (recombined) electron by the electrolyte, thereby enhancing efficiency; enlarges a size to cover a semiconductor layer surface per unit molecular by using the organic surface modifier where there are at least three functional groups (X1-X3) per one molecular capable of interacting with a hydroxyl group (-OH) existing on a semiconductor surface, thereby effectively protecting the semiconductor layer from the electrolyte; and uses an insulation material with large electron blocking effect, not a metallic oxide, as the organic surface modifier, thereby introducing the insulation material on the surface of the semiconductor layer by a simple deposition process, not a high temperature plasticizing process and also enhancing efficiency of the solar cell.
