| Popis: | 95 The life of mankind with the development of the technology becomes more convenience and comfortable. It also makes us to need more energy, and the development of new energy becomes very important in this year. Recently, a new type of solar cell based on dye-sensitized nano-crystalline titanium dioxide has been developed by Grätzel and coworkers. Dye-sensitized solar cells based on nano-crystalline TiO2 electrodes are currently attracting widespread attention as a low cost alternative to conventional inorganic photovoltaic devices. In this research, applications of TiO2 nanotube electrode structures on Dye-Sensitized Solar Cell were investigated. The main items include (1) Use the gel polymer electrolyte to improve the difficult question and easy seepage of liquid electrolyte encapsulation. (2) Prevent the electrolyte and ITO-glass from being exposed to directly but reduce the efficiency of the solar cells.(3) Improve electrons and transmit in the route and raise the efficiency effectively. We investigate these TiO2 photoelectrode structures by X-ray diffraction (XRD), Field Emission Scanning Electron Microscope(FE-SEM), Ultraviolet-Visible spectrophotometer (UV/Vis spectrophotometer), efficiency. These results provide clear evidence for the contact area between TiO2 electrode and TCPP sensitizer plays an important role on the efficiency of dye-sensitized solar cell. |
