Abstract

Research to utilize natural polymers continues to be driven primarily by utilization as an environmental friendly energy-generating and storage material. The high porosity makes cellulose acetate (CA) a good candidate as a dielectric material as the basis of the supercapacitor device. Various dopants and compositions have been widely used, but the nano size morphological differences of the same material are rarely reported. Two types of ZnO are prepared, i.e., nanoparticles and nanorods deposited with CA and deposited on ITO glass substrate. The CA-ZnO / ITO composite film was fabricated through spin coating technique. This study focused on ZnO morphological difference on the microstructure and the dielectricity of CA-ZnO /ITO composite films. The morphology of nanoparticles and nanorods of ZnO were analyzed more detail with respect to its microstructure and dielectric properties. It is revealed that the change of ZnO morphology from nanoparticles to nanorod increase the capacitance and dielectric constant significantly from the order of the nano to the micro and decrease the dielectric loss. The dielectric constant of CA-ZnONP/ITO and CA-ZnONR/ITO are respectively of 2569 and 97159 at 100 Hz. The capacitance and dielectric loss of CA-ZnONP/ITO and CA-ZnONR/ITO reach to 69.809 nF; 678 and 2,15765 µF; 13,23 respectively.

Abstract

IntisariArtikel ini membahas fabrikasi Dye Sensitized Solar Cell (DSSC) dengan menggunakan campuran dye antosianin dan klorofil sebagai fotosensitizer. Pencampuran dye bertujuan untuk memperlebar daerah serapan dye alami. Antosianin diekstraksi dari kol merah sedangkan klorofil dari daun bayam dengan metode maserasi. Komposisi dye divariasikan dengan perbandingan larutan antosianin:klorofil, yaitu 1:3, 1:1, dan 3:1. Variasi komposisi dilakukan untuk mengetahui pengaruh perubahan serapan dye terhadap efisiensi DSSC. Karakterisasi sifat optik menggunakan spektrofotometer UV-Vis, sedangkan karakterisasi sifat listrik denganI-V meter. Hasil karakterisasi menunjukkanbahwa pada perbandingan 1:3memiliki absorbansi tertinggi pada rentang panjang gelombang 400 nm hingga 450 nm dan efisiensi sebesar0,15%.ABSTRACTThis article is about fabrication of Dye Sensitized Solar Cell (DSSC) using mixture of anthocyanin and chlorophyllas fotosensitizer. Mixing dye aims to widen the absorbance area of natural dye.Anthocyanin is extracted from red cabbage andchlorophyll from spinach leaves with maseration methode. Mixture composition of dye anthocyanin:chlorophyll varying at 1:3, 1:1, and 3:1. Composition variation is performed to determine the effect of absorbance change on the efficiency of DSSC. Optic characterization using UV-Vis spectrophotometer and electric characterization using I-V meter. The characterization result showed that rasio 1:3 hasthe highest absorbance at wavelength 400 nm to 450 nm with highest efficiency 0,15%.
