Abstract:
In a method of manufacturing a photoelectric device, a transparent conductive layer is formed on a substrate, and the transparent conductive layer is partially etched using an etching solution including hydrofluoric acid. Thus, a transparent electrode having a concavo-convex pattern on its surface is formed. When the transparent conductive layer is partially etched, a haze of the transparent electrode may be controlled by adjusting an etching time of the transparent conductive layer. Also, since the etching solution is sprayed to the transparent conductive layer to etch the transparent conductive layer, the concavo-convex pattern on the surface of the transparent electrode may be easily formed even though the size of the substrate increases.
