Graphene is a potential material to replace indium tin oxide (ITO) and fluorine tin oxide (FTO) as a transparent conductive films (TCF) due to its high conductivity and transparency. In this study, fabrication of graphene-based TCF was carried out by means of the drop-casting method, with graphite oxide as the raw material. The graphene oxide (GO) was diluted by adding 1, 3, 5, and 7 ml of distilled (DI) water. The sample was also heat treated to ensure complete reduction process. The deposited films were characterized using UV-Vis spectroscopy and I-V to investigate their optical and electrical properties. Based on the measurement results, sample with 3 ml DI water addition gives transparency and sheet resistance (Rs) of 41.01 % and 9.43 kΩ/sq, respectively. This material has a great potential to be applied as the optoelectronics material.
