Abstract
Provided are a method for antireflection treatment of a zinc oxide film and a method for manufacturing a solar cell using the same. In the anti-reflection treatment, a substrate is prepared, then a polycrystalline zinc oxide film is formed on the substrate. A surface of the polycrystalline zinc oxide film is textured. Here, the roughening of the surface of the polycrystalline zinc oxide film comprises wet-etching the polycrystalline zinc oxide film on the substrate using an etching solution mixed with nitric acid and hydrogen peroxide.
