Abstract
A method for preparing a film of a CIS semiconductor compound overcoated by a color layer includes preparing an electrolyte solution by mixing precursors of film constituents including Cu, In, and Se with a solvent; configuring an electrodeposition circuit by connecting an electrochemical cell comprising the electrolyte solution, a working electrode, and a counter electrode to a voltage or current supply device; disposing a photomask having the predetermined pattern on the working electrode; producing the film through the photomask on a surface of the working electrode by applying a reduction voltage or current; disposing a light source to emit light toward the photomask; and photoelectrically depositing the film on the surface of the working electrode at least in the predetermined pattern while illuminating light through the photomask; and forming a color layer of CuSe at least in the predetermined pattern on the film employed as a working electrode using photo-electrodeposition.
