    Abstract

    Dye-Sensitized Solar Cell (DSSC) is a solar cell device capable of converting solar energy into electrical energy by utilizing natural dyes in absorbing photons. Components of the DSSC are dye, photoelectrode, electrolyte and counter electrode deposition on a conductive substrate. Photoelectrode in this research is Titanium dioxide (TiO2) which inserted copper and soaked in dye. The purpose of research is to obtain DSSC performance from photoelectrode in the insertion of copper on TiO2 by making Cu/TiO2 nanocomposite and the electroplating method. The nanocomposite is the process of mixing different materials or materials that are nano-sized. Electroplating method is a method of metal coating with the help of electric current in the conductive solid object. Variations in the manufacture of Cu/TiO2 nanocomposite are the variation of the mass ratio of TiO2 : copper and variations of electroplating method are electroplating time of copper on TiO2. Natural dyes used are Moringa oleifera leaf extract. The photoelectrode is copper inserted on TiO2. The electrolyte used is NAI and the counter electrode is Pt. The purpose of the research can be obtained from the results of the characterization of absorbance spectrum, conductivity, SEM, XRD and voltage-current (I-V). The results obtained from the absorbance characterization which has the highest absorbance on the manufacture of Cu/TiO2 nanocomposite is the ratio of 8: 3 (TiO2: Cu) and through the electroplating method is at insertion time 25 s. The result of conductivity characterization which has the highest conductivity in making Cu/TiO2 nanocomposite is the ratio of 8: 3 equal to 5.14 Ω^(-1) m^(-1). The XRD results show that there is the insertion of copper on TiO2 through both methods with the appearance of rutile phase and copper diffraction pattern. The result of I-V characterization obtained the highest efficiency in making Cu/TiO2 nanocomposite that is the ratio of 8: 3 (TiO2: Cu) equal to 0,048% and by electroplating method that is at time of insertion 25 s equal to 0,090%.
