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

We report the structural properties of TiO2 (Titanium dioxide) thin films grown using sol-gel spin coating method for temperature treatment (with temperature 50o C and without temperature) The difference in temperature is carried out to determine changes in the surface of the sample by using heating or not. Ideally, the thickness of the TiO2 layer ranges from 10-15 μm, therefore in this study it was carried out in 5 layers. Field Emission Scanning Electron Microscopy (FESEM) consist of surface morphology, Cross-section sample, and EDX images, respectively, providing the structure of the surface. The result confirm that temperature treatment can damage the surface coating, this is proven by the shape of the crack in the coating.
