SOLAR CELL HAVING CUPROUS OXIDE THIN FILM

摘要

A solar cell according to one embodiment of the present invention comprises a substrate; a first electrode on the substrate; a second electrode on the first electrode; a light absorption layer between the first electrode and the second electrode; and a copper-oxide thin film in contact with at least one surface of the first electrode and the second electrode. The present invention can make various and detailed color by controlling the thickness of the copper-oxide thin film and an oxygen ratio. Furthermore, the present invention improves the light efficiency of the solar cell by providing anti-reflection films at the same time according to the positions.
