Abstract
The present invention relates to a substrate for a photoelectric device and a photoelectric device comprising the same and, more specifically, to a substrate for a photoelectric device and a photoelectric device comprising the same capable of guaranteeing the flatness of thin-films forming the photoelectric device and the structural stability of a functional thin-film formed to improve the characteristics of the photoelectric device, thereby maintaining the function of the functional thin-film. To this end, the present invention provides a substrate for a photoelectric device and a photoelectric device comprising the same, the substrate comprising: a base substrate; a concave-convex structure formed on the base substrate, in which the surface of the concave-convex structure forms a concave-convex pattern; and a planarization layer formed on the concave-convex structure, the planarization layer being formed of a 2-dimensional material.
