Simulation of 3-domain Dye-sensitized Solar Cells Based on Nanostructure

The DSCs(dye-sensitized solar cells) have drawn much attention to many researchers in recent years due to their simple process,low cost and potential excellent performance.In this paper,an appropriate electrical model has been presented.The solar cell is modeled by three parts which are TiO2 semiconductor,pseudo-homogeneous effective medium and redox electrolyte.The charge carriers continuity,transport and Poisson′s equations are all applied.As a result,the model demonstrates electrical characteristics inside the cell and the influence of the nanotubes′ length on the cell performance successfully.
