CIGS LIGHT-ABSORBING INK AND METHOD FOR PREPARING CIGS LIGHT-ABSORBING LAYER

摘要

The present invention relates to a method for preparing a CIS-based 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-based 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 sulfuration treatment or selenium treatment is made optional, not requisite.
