Abstract

Surface Plasmon Resonance (SPR) phenomenon of the oxidizing and reducing polypyrrole (PPy) have been observed using a modified Au/PPy Kretschmann configuration. The observation was carried out through simulation Winspall 3.02 software and compared with some experimental data refractive index (n), absorbance index (), and thickness (τ) reported in other literatures with spectroscopy ellipsometry. This simulation assumed that the SPR system use BK-7 halfcylinder prism (n= 1,515) and the laser beam was generated by HeNe (λ= 632,8 nm). The result showed that the optimum layer thickness of polypyrrole with neutral electrolyte solution in the reduction state is of about 20 nm. The polypyrrole with an acid solution in the oxidation state showed that the reflectivity curve is sharper and the width of the curve is smaller than the neutral electrolyte solution in the reduction state with the SPR angle of about 46,810 and the reflectivity value of about 0,217. Polypyrrole in a state of oxidation and reduction, related to the absorption, film thickness, and dielectric constant of materials, affected to the SPR angle shift and dip curve

Abstract

DSSC (Dye Sensitized Solar Cell) uses dye as a sensitizer material which is used as an electron donor to TiO2 nanoparticles and uses an electrolyte as an electron transport medium. One of the dye extracts of purple spinach and moringa leaves used as a photosensitizer is chlorophyll extract or anthocyanin. The nature of chlorophyll which is able to absorb light is a function of the dye in DSSC. Making Moringa leaf and red spinach leaf dye after being blended, dried and ground into powder. Then the Moringa leaf powder was mixed with 70% ethanol with the ratio of Moringa leaves and ethanol, namely 1:2, 1:3, and 1:4. Meanwhile, red spinach leaf powder was mixed with ethanol solution in a ratio of 1:3. DSSC fabrication shows that the voltage, current, and power produced increases with the increasing amount of ethanol used, namely 1.879 mW, 1.573 mW, and 1.98 mW. Meanwhile, red spinach leaves mixed with ethanol in a ratio of 1:3 showed that the results were higher than Moringa leaves. So from the results of DSSC Solar Cell fabrication using Moringa leaves and red spinach leaves, it shows that there is light absorption from these materials and an increase in the conductive properties of Moringa and red spinach DSSCs.
