註釋The distribution of the components in the dye-sensitized titanium dioxide solar cell (DSC) is investigated in the thesis. The transport and drift of the ions (iodide, triiodide and cathion) in the electrolyte and the electrons in the nanocrystalline titanium dioxide semiconductor were modeled in the operation of the cell. Homogenization is used to reduce the three dimensional solar cell into a one dimensional system along the thickness of the cell. The model includes both the porous semiconductor and the bulk electrolyte layer between the semiconductor and the cathode. The influence of the parameters of the cell on electron concentration profile is investigated. In particular, the influence of the electron lifetime and the thickness of the nanocrytalline semiconductor are investigated. We applied boundary layer techniques in the solution of the resulting system.
