A manufacturing method of a polymer solar cell is illustrated. A substrate and a first conductive layer formed thereon are provided. An organic active semiconductor material and a functional organic material, which features modifying an interface between an organic layer and electrodes, are dissolved in an organic solvent to form a blend. The blend is deposited on the first conductive layer by solution process. The organic solvent is removed, such that the functional organic material and the organic active semiconductor material exhibit phase separation so as to form an organic modified layer on the top of the organic active semiconductor layer. A second conductive layer is deposited by thermal coating on the organic modified layer. Importantly, the organic modified layer formed by spontaneous phase separation effectively modifies the interface between the organic active semiconductor layer and a second conductive layer, thereby enhancing efficiency of an organic solar cell.
