    Abstract: The present invention relates to a method of fabricating chalcopyrite compound (for example, CIS, CIGS, CIS, or CIGS) thin films for solar cells using multi-stage paste coating which are applied to a light absorption layer in a thin film solar cell. More particularly, the present invention relates to a method for improving the efficiency of a solar cell by using a chalcopyrite compound film manufactured by multi-stage coating of ink or a precursor solution paste which has different physical properties in a method of manufacturing a solution process based light absorption layer such as printing for manufacturing a low cost thin film solar cell. [Reference numerals] (100) Manufacturing a Cu, In, Ga mixed precursor paste 1; (102) Manufacturing a Cu, In, Ga mixed precursor paste 2; (103) Coating the paste 1; (104) Drying; (105) Coating the paste 2; (106) Thermal treatment 1 Cu, In, Ga mixed oxide thin film; (107) Thermal treatment 2 CIGS thin film
