Abstract

The extraction of natural dyes was carried out on plants with different types of natural dyes. Dye curcumin from turmeric extract (Curcuma longa), chlorophyll dye extraction of alga (Bryophyta), and anthocyanin  dye from red cabbage plants (brassica oleracea) and adam eva plant (tradescantia spathacea). The trituration of each plant was then extracted using ethanol in a ratio of 1 gr: 5 ml with a stirring process for 24 hours. Measurement absorption ability of natural dyes was done using the UV-Visible Lambda Spectrophotometer 25. The peak absorption of dye curcumin was in the wavelength range of 350-500 nm with the peak wave absorbance at 447 nm. The peak absorption of anthocyanin red cabbage dye is in the wavelength range of 327-384 nm. Dye chlorophyll and anthocyanin dye of adam eva plant had wavelength absorbance in the range of visible light and infrared with absorbance peaks at 419 nm and 674 nm.

Abstract

Electrospinning is a modified technology to produce nano-sized fibers which can be used in making thin layers of semiconductor dye sensitized solar cells. Flourate – doped tin oxide (FTO) substrate was placed as a target for deposition of TiO2 nanofiber synthesized from TiO2 solution. The deposition process of a thin layer of TiO2 nanofiber was carried out for 15 minutes. The TiO2 solution synthesized is a mixture of acetic acid, ethanol, polyvinylpyrrolidone (PVP), and titanium tetra – isopropoxide (TTIP). Mixing the synthesis solution was carried out for 24 hours, to obtain a homogeneous TiO2 synthesis solution. The TiO2 nanofiber thin layer deposition process was applied under an electrospinning voltage of 25 kV, the distance of the FTO substrate as the collector layer to the solution syringe was 25 cm to avoid too large solution droplets. Before the deposition stage, the surface of the FTO substrate is first formed using the etching method by coating Zn and removing the conductive layer using HCl, so that a customized conductive layer is obtained. The annealing process of the deposited TiO2 nanofiber layer was carried out for 3 hours at a temperature of 450°C. The spin coating method was carried out to deposit a layer of Poly [2- methoxy- 5- (2- ethyl hexyloxy)- 1,4- phenylene venylene] (MEH-PPV). Coating variations are carried out with 4 different layer thicknesses. MEH – PPV was prepared by mixing chlorobenzene and stirring for 18 hours. Testing and characterization was carried out using current and voltage characterization (I – V meter), as well as image characterization using Scanning Electron Microscopy (SEM) as an analysis of the influence of layers on organic solar cells.
