Abstract The developed numerical model of dye-sensitized solar cell based on titanium dioxide (TiO2) to build its theoretical current-voltage and power-voltage characteristics and determine its basic photovoltaic parameters such as short-circuit current density , open circuit voltage, maximum power density and conversion efficiency. Developed a numerical model based on a system of stationary one-dimensional differential equations of continuity, describing the generation, recombination, and transport of charge carriers (electrons and ions) in the structure of nanoporous TiO2, a sensitizing dye and the redox electrolyte. In this model included expressions for calculation of the coefficient of absorption solar radiation on the porosity of the film structure TiO2, the photon flux density in the spectral absorption of the dye molecules and the sequence of resistance in a solar cell on its topological dimension. Solution of differential equations of the model was carried out with the boundary conditions corresponding to the three basic modes of operation of the solar cell. As a result of numerical simulation found that the theoretical characteristics and photovoltaic solar cell parameters investigated are fully consistent with the presented experimental data.
