CIGS THIN FILM FABRICATING METHOD AND OPTICAL ABSORBER LAYER FABRICATED USING THE SAME

摘要

PURPOSE: A CIGS thin film fabricating method and an optical absorber layer fabricated using the same are provided to improve the performance of the CIGS thin film by manufacturing the CIGS film through an electrophoresis. CONSTITUTION: A CIGS thin film fabricating method and an optical absorber layer fabricated using the same are comprised of the steps: manufacturing a mixed solution by mixing a copper material precursor, an indium raw material precursor, a gallium material precursor, and a selenium raw material precursor with water or a buffer solution; dipping a working electrode and an opposite electrode to the working electrode into a mixed solution; and applying a voltage to a potentiostat and making CIGS film electroplated on the working electrode.
