FABRICATION METHOD OF CIGS THIN FILMS AND ITS APPLICATION TO THIN FILM SOLAR CELLS

摘要

The present invention relates to a method for manufacturing a CIGS thin-film capable of compensating for grain boundary defect problems and increasing the conversion efficiency of a thin-film solar cell accordingly, a thin-film solar cell manufacturing method using the same, and the thin-film solar cell thereof. According to the present invention, the CIGS thin-film manufacturing method includes: a substrate mounting step of mounting a substrate on a sputtering apparatus; and a CIGS thin-film deposition step of sputtering a single CIGS target through a single sputtering process to deposit the CIGS thin-film on the substrate.
