Solar cell is an environmental friendly technology used in many industries and household as an electricity source. The cell works by converting solar radiation directly to electric energy. The most common solar cell is silicon based solar cell. However, the fabrication of siliconbased solar cell is expensive. The main difference between DSSC and common solar cell is the use of dye to enhance cell’s sensitivity. In DSSC, the counter electrode is made from platinum which is very expensive. To overcome the problem, carbon is being used to substitute platinum as counter electrode. This research is focused on carbon electrode fabrication method and sources of carbon. The experimented-fabrication methods are metering rod, doctor blade and bubble deposition, while the source of carbon used are medicinal activated carbon and commercial activated carbon. DSSC performance are characterized using I-V curve and electrochemical impedance. Moreover, carbon electrode morphology are observed using Scanning Electron Microscopy (SEM) while carbon electrode surface area and porosity are observed using BrunauerEmmett-Teller (BET). <br /> <br /> <br /> Based on the research results, DSSC fabricated with bubble deposition method yield the highest efficiency. Meanwhile, medicinal activated carbon provides better efficiency than commercial activated carbon. The highest conversion efficiency of solar energy achieved is 3,763%
