Electrodeposition of diamond-like carbon thin film on conductive indium-tin-oxide glass substrate

Abstract

This paper presents electrodeposition of diamond-like carbon (DLC) thin film deposits on indium tin oxide (ITO) glass substrate under voltage 2.1V∼120V with mixing varying acetic acids' portions with deionized water, forming 0.2∼0.8% electrolytic solutions. The result shows that at deposition temperature 30°∼65°, voltage 50V and 0.8% electrolytic solution concentration of DLC thin films, the reflection index reduced to 60%, and theoretical matching refractive index became 1.32. This finding is applicable on various optoelectronic device like protective or window layer of solar cell.
