A method for manufacturing an organic-inorganic hybrid solar cell, the method including forming a first electrode, forming a first common layer on the first electrode, forming a first light absorbing layer by applying a first perovskite precursor solution including a first organic halide and a first metal halide on the first common layer, forming a second light absorbing layer by applying a second perovskite precursor solution including a second organic halide on the first light absorbing layer, forming a second common layer on the second light absorbing layer; and forming a second electrode on the second common layer.
