Abstract
The present invention relates to a method for preparing a CIS- or CIGS-based light-absorbing layer which is included in a thin film solar cell. More particularly, the present invention relates to a method for preparing a CIS- or CIGS-based light-absorbing layer which ultimately improves the efficiency of a solar cell since the remaining carbon impurities in the formed light-absorbing layer are minimized and additional sulfurization treatment or selenium treatment is made optional, not requisite.
