Abstract

Research on the performance of Dye Sensitized Solar Cell (DSSC) using single dye, mixture of anthocyanin and chlorophyll has been done. The purpose of this study was to identification influence the type of dye to the working efficiency of DSSC. This research included in experimental research. The working electrode of DSSC was made of dyes from dragon fruit, red spinach, pandanus leaves, cassava leaves and made of TiO2 semiconductor that superimposed with doctor blade method on FTO glass. While the counter electrode was made of 2B pencil carbon-soot a candle flame. Measurements absorbance of each type of dye using spectrophotometer UV-Vis to determine the absorbance values of each type of dye, the highest absorbance at dye mixture from dragon fruit- pandanus leaves. Measurement of currents and voltages using a multimeter with a light source of the sun to determine the efficiency of DSSC, the best efficiency values obtained in DSSC that used dye mixture from dragon fruit-pandanus leaves is equel to 0,002829091% and red spinach-cassava leaves is equel to 0,002222504%. The usage of dye mixture can improve efficiency of DSSC.

Abstract

This research aimed to produce magnetites from the residue of iron sand extract solution in HCl and the effect of silica encapsulation on the magnetite used XRD, SEM and FTIR characterization tools. The crystal size tended to increase in the magnetite encapsulated by silica (K (6%), L (9%), N (24%) and O (36%), because the perfect condensation and hydrolysis of the encapsulation material, while the M sample (12%) decreased the crystal size of 17.41 nm because the hydrolysis and condensation of the sample did not occur completely. The crystals in magnetite before and after being encapsulated with silica did not change. The transmittance of the typical functional groups of magnetite (Fe-O) and the typical functional groups of silica (Si-O-Si) tends to decrease after encapsulation with silica which caused the infrared absorbance of the molecules to increase high so that the presence of magnetite and silica is higher in the silica encapsulated sample The effect of variations in silica concentration on SEM characterization results is reduced agglomeration, particles that coincide and stick to the sample as the silica concentration increased with the smallest particle size found in the M sample (12%), namely the range of 10-50 nm. The residue of the iron sand extract solution with HCl can form nanomagnetites with an average particle size range below 100 nm.
