Physics based simulation of dye solar cells

Dye sensitized solar cells are interesting candidates for providing a renewable, cost efficient energy source with low environmental impact. The lack of a suitable simulation software to study basic cell properties and to optimize the cell topology is currently one of the factors hindering their commercialization. We present in this paper a theoretical model of the entire device based on drift-diffusion equations. The model, implemented within TiberCAD software package, is used to investigate the impact of important parameters of the cell like electron mobility, recombination rate constant and TiO 2 roughness on the overall efficiency of the cell.
