Abstract
One of the easy and cheap solar cell is Dye sensitized solar cell (DSSC) that use dye to harvest sun-s energy. It has drawback in low efficiency because of electron recombination occurrence and low transparence of photoanode. Reduced graphene oxide as derivative of graphene was hoped to overcome the problems. This research is aimed to study the effect of nanocomposite Titanium Oxide-reduced Graphene Oxide (TiO2-rGO) as photoanode to the efficiency by varying the percentage of rGO that fabricated by Hummer-s Method. The rGO from Graphite is successfully fabricated that confirmed from FTIR and SEM and TiO2-rGO nanocomposite has been fabricated and characterized using UV-Vis. The nanocomposite has been used as photoanode that affect the efficiency. The result shows the effect of percentage of rGO on the performance. The efficiency of solar cell is measured using solar cell simulator and give result for 0% rGO resulted 1.45 % efficiency and 0.664% that for 1% rGO. The moderate result is 2% of rGO that resulted 0.9 % efficiency. The pattern is not regular but the effects is counted
