Abstract
A method for manufacturing a light absorption layer of a thin film solar cell in in a method for manufacturing a solar cell transparent electrode may be provided that includes: manufacturing a Ib group element-VIa group element binary system nano particle (s100); manufacturing a binary system nano particle slurry of the Ib group element-VIa group element by adding a solvent, binder and a solution precursor including Va group element to the Ib group element-VIa group element binary system nano particle (s200); distributing and mixing the binary system nano particle slurry of the Ib group element-VIa group element (s300); coating the binary system nano particle slurry of the Ib group element-VIa group element on the rear electrode layer 200 (s400); and performing a heat treatment process on the coated nano particle slurry by supplying the VIa group element (s500).
