METHOD FOR MANUFACTURING LIGHT ABSORPTION LAYER OF THIN FILM SOLAR CELL AND THIN FILM SOLAR CELL USING THE SAME

摘要

A method for manufacturing a light absorption layer of a thin film solar cell includes: manufacturing a Ib group element-VIa group element binary system nano particle; manufacturing a binary system nano particle slurry of the Ib group element-VIa group element by adding a solution precursor including a solvent, binder and Va group element to the Ib group element-VIa group element binary system nano particle; distributing and mixing the binary system nano particle slurry of the Ib group element-VIa group element; coating the binary system nano particle slurry of the Ib group element-VIa group element on the rear electrode layer; and performing a heat treatment process on the coated nano particle slurry by supplying the VIa group element.
