불소 도핑 TiO2 염료감응형 태양전지의 전기화학적 특성 = Electrochemical Characterization of Fluorine Doped TiO2 Dye-Sensitized Solar Cells

다국어 초록 (Multilingual Abstract)

In this study, the fluorine doped TiO2 was prepared as a photoelectrode in order to improve the efficiency of dye-sensitized solar cells and estimated the electrochemical characterizations. The energy conversion efficiency of the prepared dye-sensitized solar cells using fluorine doped TiO2 was calculated from a current-voltage curve. The efficiency of prepared dye-sensitized solar cells was improved by about maximum three times by F-doping on TiO2. It was suggested that the efficiency of dye-sensitized solar cells was improved by hybrid semiconductors of TiO2/TiOF2 in photoelectrode based on reduced TiOF2 energy level via fluorine doping. It can be confirmed that the electron transport was faster but the electron recombination was slower by doping fluorine on TiO2 in photoelectrode through intensity-modulated photocurrent spectroscopy and intensity-modulated photovoltage spectroscopy analysis.
