Abstract
A transparent conductive oxide thin film substrate that has a high level of surface flatness, a method of fabricating the same, and an OLED and photovoltaic cell having the same. The transparent conductive oxide thin film substrate that includes a base substrate, a first transparent conductive oxide thin film formed on the base substrate, the first transparent conductive oxide thin film being treated with a first dopant, and a second transparent conductive oxide thin film formed on the first transparent conductive oxide thin film. The second transparent conductive oxide thin film is treated with a second dopant at a higher concentration than the first dopant. The surface of the second transparent conductive oxide thin film is flatter than the surface of the first transparent conductive oxide thin film.
Description
[0001] Cross references to related patent applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0082293 filed on Jul. 27, 2012, the entire contents of which are hereby incorporated by reference in all respects. technical field [0003] The present invention relates to a transparent conductive oxide thin film substrate, a method for manufacturing the substrate, and an organic light emitting device (OLED) and a photovoltaic cell having the substrate, and more particularly, to a transparent conductive oxide thin film substrate having a high level of surface flatness, A method for manufacturing the substrate, and an OLED and a photovoltaic cell having the substrate.
