    • The present invention relates to a thin film solar cell and, specifically, to a method for manufacturing a thin film having an optical absorption layer including group Ib elements, group VIa elements, and group Va elements; and a thin film solar cell using the same. The present invention provides a method for manufacturing a transparent electrode of the solar cell, and particularly a method for manufacturing the optical absorption layer of the thin film solar cell, including: a substrate (100); a back side electrode layer (200) formed on the substrate; the optical absorption layer (300) formed on the back side electrode layer (200); a buffer layer (400) formed on the optical absorption layer; and a transparent electrode layer (500) formed on the buffer layer (400). The method for manufacturing the optical absorption layer of the thin film solar cell comprises the steps of: manufacturing binary nanoparticles of the group Ib elements-the group VIa elements (s100); adding a solvent, a binder, and a solution precursor including the group Va elements to the binary nanoparticles of the group Ib elements-the group VIa elements to manufacture binary nanoparticles slurry of the group Ib elements-the group VIa elements (s200); dispersing and mixing the binary nanoparticles slurry of the group Ib elements-the group VIa elements (s300); coating the binary nanoparticles slurry of the group Ib elements-the group VIa elements on the back side electrode layer (200) (s400); and heat-treating the coated nanoparticles slurry while supplying the group VIa elements (s500).
