Abstract
Disclosed are an ink composition for manufacturing a light absorption layer of solar cells and a method of manufacturing a thin film using the same. Particularly, an ink composition for manufacturing a light absorption layer of solar cells including core-shell structure nanoparticles including a core including a copper (Cu)-containing chalcogenide and a shell including a zinc (Zn)-containing chalcogenide; and tin (Sn)-containing bimetallic or intermetallic metal nanoparticles, or a tin (Sn)-containing chalcogenide nanoparticles, dispersed in a solvent, and a method of manufacturing a thin film using the same are disclosed.
