Abstract

This research studied the effect of adding synthetic dye DN-F05 (red dye) to electrical and optical properties. Dye-Sensitized Solar Cell (DSSC) sandwich components are consist of FTO/TiO2-Dye-elektrolit-Platina/FTO. In this study, the working electrodes were made by Titanium dioxide (TiO2) which was deposited on FTO glass and then annealed at 450oC for 30 minutes. The dye concentration DN-F05 was made with a mass of 0.001 gr, then will be stirred for 2 hours into 5 ml of ethanol at a temperature of 40oC. In this study the spin coating method is used with a rotational speed of 1000 rpm for 20 seconds. Characterization of optical properties was carried out using a UV-VIS spectrophotometer to determine the absorbance curve of dye and to get Gap energy. The peak absorbance value was obtained at wavelengths between 400-700 nm. This proved that the addition of DN-F05 dye concentration has a major influence on the optical properties.

Abstract

Dye-Sensitized Solar Cell (DSSC) is a solar cell made from organic material that works with an electrochemical photo system to convert solar energy into electrical energy. The components of DSSC consist of transparent conductive substrates, dyes, semiconductors, electrolytes and counter electrodes. Dye as a sensitizer is has an important role in DSSC performance improvement. This study aims to obtain optical characterization such as absorbance spectrum and transmittance from DSSC using dye DN-F01 with concentration 2x10-3 M. Optical characterization has been tested using a UV-VIS Spectrophotometer Shimadzu UV-1800. The test results show that the absorbance spectrum of the dye is at a wavelength of 400-500 nm. Band gap energy of DN-F01 has obtained  from its absorbance and transmittance value is about 2,46 eV.

Abstract

Dye sensitized solar cell (DSSC) is the third generation of solar cells that currently developing by researchers to get the best performance. The selection of dye as a component of DSSC has a big influence in the light absorption process. In this study, DN-F01 organic dye was used as a sensitizer with various concentrations. The optical properties test was carried out on the DN-F01 dye solution by UV-Vis spectrophotometer (Shimadzu UV-1800) and the DSSC fabricated performance was tested by portable solar simulator (ORIEL Sol1A). From the results, the DN-F01 absorbance has ability to absorb light in the 300-500 nm wavelength range. The greatest efficiency value in this research is 2.44% obtained from the sample was immersed with the largest concentration of dye DN-F01 which has the smallest band gap energy of 2.38 eV.
