| 제목 | The study on Improvement of the efficiency of dye-sensitized solar cell with mesoporous TiO2 /TiO2 nanoparticle mixed electrodes depending on mixing ratios |
| 초록 | For improve the efficiency of DSSC, the amount of dye adsorbed and lower contact resistance are necessary. To obtain larger surface area for adsorbing more dye molecules, mesoporous TiO2 (meso-TiO2) is used for DSSC, but due to the large size difference between meso-TiO2 and P25 (nano-TiO2), there is larger contact resistance. More empty space declines the transfer rate of electron between TiO2. To reduce contact resistance, addition of nano-TiO2 into meso-TiO2 electrode could reduce the contact resistance. Furthermore, added nano-TiO2s adsorb dyes, total amount of adsorbed dyes could be increased. The result is that 65wt% of meso-TiO2 with 35wt% of nano-TiO2 electrode shows the highest efficiency. The characterization of electrodes and DSSC was done by X-ray diffraction (XRD), N2-sorption isotherm, UV-Vis spectrometer, Scanning Electron Microscopy (SEM), Impedance measurement, solar simulator, incident photon to charge carrier efficiency (IPCE) and Diffuse Reflectance UV-Visible Spectra (DRS). |
