Abstract: The present invention discloses a method for preparing a compound thin film, a compound thin film prepared therefrom, and a solar cell including the compound thin film. An exemplary embodiment of the present invention provides a method for preparing a compound thin film, the method including: an electrolyte solution preparation step; a circuit configuration step; and a thin film production step in which a compound thin film with a specific pattern provided on the surface thereof is produced according to the difference in the thickness of the thin film between a region where light arrives and a region where light does not arrive.
