Provided are a method for preparing a CI (G) S based thin film using a binary component nanoparticle hybrid method and a CI (G) S based thin film prepared by the method. The method for producing a CI (G) S-based thin film of the present invention comprises the steps of preparing a CI (G) S-based bicomponent nanoparticles; Preparing a hybrid slurry by mixing two-component nanoparticles, a solution precursor containing a CI (G) S-based element, a solvent, and a binder; Coating a hybrid slurry to form a CI (G) S-based thin film; And heat-treating the formed CIGS thin film. As a result, pores in the thin film can be minimized, particle growth can be improved, and the structure of the thin film can be densified, thereby ultimately increasing the efficiency of the solar cell using the thin film. |
