    Abstract: The present invention relates to an organic solar cell to introduce an exciton blocking layer on both a hole extraction layer and an electron extraction layer and, more particularly, to an organic solar cell which is composed of hole and electron exciton blocking layers on two metal layers and a light absorption layer which is formed by a bulk heterojunction. Charges generated by light are smoothly moved by smoothing transporting the charges by simultaneously introducing a hole transport layer and an electron transport layer for an exciton blocking layer with a high charge transport property. If materials with a large energy level difference are used, the light conversion efficiency of the solar cell is improved by blocking a leakage current.
