Abstract

Disclosed are an aggregated precursor for manufacturing a light absorption layer of solar cells comprising a first phase comprising a copper (Cu)-containing chalcogenide and a second phase comprising an indium (In) and/or gallium (Ga)-containing chalcogenide wherein 30% or more aggregated precursors based on the total amount of precursors are divided into particle aggregates comprising first phases and/or second phases, or independent particles having first phases or second phases, in an ink solvent for manufacturing the light absorption layer, and a method of manufacturing the same.
