A computer simulation method of dye-sensitized nanocrystalline solar cells

A computer simulation of dye-sensitized nanocrystalline solar cells is presented. Specifically, formulation and a numerical simulation method are described in detail. The theoretical model consists of the following differential equations: an equation for charge conservation, current equations for electrons in semiconductor matrixes and ion species in electrolytes, and an equation for charge separations in the sensitized electrodes. The differential equations are solved with the Newton-Raphson method after discretization of the equations. A simulation of current-voltage characteristics of the dye-sensitized solar cells is presented. Limitations of the model are also described.
