본문내용

A TiO2 blocking _badtags in DSSC provides good adhesion between the fluorinated tin oxide (FTO) and an active TiO2 _badtags, and represses the electron back transport between electrolyte and FTO by blocking direct contact. In addition, it offers a more uniform _badtags than bare FTO glass. In this study, a dense TiO2 _badtags is prepared by electrodeposition technique onto an FTO substrate, and it is further used for efficiency measurement of dye-sensitized solar cell (DSSC). The thickness of TiO2 blocking _badtagss is controlled by applied voltage and deposition time. The morphology and crystalline structure of TiO2 blocking _badtagss are characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray diffraction (XRD). The effect of thickness of TiO2 blocking _badtagss on transmittance is also examined by UV-vis spectrophotometer. For the best performance of the cell efficiency, the optimum blocking _badtags thickness is about 450 nm fabricated at 0.7 V for 20 min.
