METHOD FOR PRODUCING COMPOUND THIN FILM HAVING SURFACE PATTERN COMPOUND THIN FILM PREPARED THEREFROM AND SOLAR CELL COMPRISING THE COMPOUND THIN FILM

摘要

Disclosed are a compound thin film manufacturing method, a compound thin film manufactured thereby, and a solar cell including the same. According to one embodiment of the present invention, the compound thin film manufacturing method comprises: an electrolyte solution manufacturing step; a circuit formation step; a mask mounting step; and a thin film generation step of generating a compound thin film having a predetermined pattern formed on a surface in accordance with a thickness difference between a thin film of an area where light arrives and a thin film of an area where light does not arrive. Accordingly, implemented is a method to manufacture a thin film with a growth thickness different from whether the light arrives, thereby manufacturing a compound thin film which realizes photovoltaic power generation in all areas without a loss of a material and has a pattern formed thereon, and increasing aesthetics of a solar cell including such compound thin film. Moreover, inhomogeneity in a surface composition, which can be generated by photoelectrochemical deposition of the compound thin film is removed and the compound thin film represents color by photoelectrochemical deposition of an additional coloring layer, thereby enhancing efficiency and added value of the solar cell including such compound thin film.
