The globally encountered energy crisis can be solved by utilizing sunlight as an alternative energy source. Energy from the sun can be harnessed through application on solar cell. Dye-sensitized solar cell (DSSC) is a type of solar cell which utilizes dye as light-harvester and also as sensitizer. This research aimed to investigate the usage of malabar melastome (Melastoma malabathricum) as dye material and to observe the impact of ethanol solvent’s dilution and coating thickness of TiO2 on the DSSC cell produced. Fabrication process of the cell includes several steps. First step, material preparation and dye extraction, by dissolving fruit of malabar melastome in a mixture of 40 ml ethanol, 8 ml acetic acid, and 52 ml aquadest. The next step is making of TiO2 paste by mixing 5 g of TiO2 with 40 ml solvent ethanol or aquadest accordingly to variables and deposited using spin coating method. Following step, making of electrolyte by dissolving 0,127 g of iodine in 0,5 M of KI solvent. Finally, the counter-electrode is made and the DSSC is assembled. The DSSC’s voltage is then examined using multitester and analyzed using SEM, UV-Vis spectrophotometry, and adhesion test. The higher ethanol fraction contained in the solvent and the thicker the coating of TiO2, which relates accordingly to the droplets-volume, then the better voltage resulted. This fact is supported by the morphology and adhesivity which is improved along with the increment of ethanol fraction and coating thickness. The increasing thickness also resulted in greater amount of dye adsorbed. It can be proved from the highest voltage obtained from the sample with 100% fraction of ethanol and the thickness of 240 μm equivalent to droplets-volume of 200 μl which is 659 mV/cm2 under the illumination of LED light and 1806,7 mV/cm2 when applied on direct sunlight.
