Abstract:The aims of this research are to understand the optical characteristics of SnO2 doped with Indium and Aluminum (SnO2:In+Al) using the sol-gel spin coating technique. Optical characteristics of SnO2:In+Al thin films were measured by UV-Vis Spectrophotometer. The optical characterization results showed that the SnO2:In+Al thin films had an increase in transmittance from (68.6-78.3)% at a wavelength of 300-470 nm and an increase in absorbance at a wavelength of 295 nm from 4.34-5.00 with the increase in the perce… Show more
“…The smaller the value of the activation energy possessed by a layer, the less energy is needed for a chemical reaction to occur.The use of Fluorine and Indium doping in this study seems to be able to affect the activation energy of the Titanium Dioxide thin film. The addition of Fluorine (F) doping can reduce the activation energy of the thin film from 4.04 to 1.99 eV [12], while the addition of Indium doping can reduce the activation energy of the thin film from 2.91 to 2.35 eV [38,39].…”
Research has been carried out in the form of the synthesis of a thin film of Titanium Dioxide with a mixture of Fluorine and Indium doping. The purpose of this research is to obtain the characteristics of a thin filmphotocatalyst with a crystal structure and optical properties that can be applied to solar cell components. This research was carried out in two stages, namely the synthesis stage and the thin filmcharacterization stage. The TiO2 thin film synthesis stage is through the substrate preparation process, sol-gel solution preparation, thin film deposition, and heating process, while the thin-film characterization stage uses X-Rays Diffraction (XRD) to identify crystal properties and UV-VisSpectrophotometer to determine optical properties of a thin film of TiO2 and TiO2:(F+In). Based on data analysis and discussion, XRD test results showed that the thin film of TiO2:(F+In) has an Anatase phase with a tetragonal shape, and has an average crystal size that is getting smaller from 23.14 to 12.17 nm. Based on the results of research, data analysis, and discussion, it was found that the sample of TiO2 : (F+In) has characteristics that can be used as materials in the development of solar cell components. These characteristics are like 1). havenano-sized particles, 2). have a low transmittance value and high absorbance in absorbing sunlight, and 3). have a low activation energy and energy gap (direct and indirect).
