Dye-sensitized solar cells (DSSCs) are a newer generation of solar cells that, although they have lower efficiency compared to silicon-based solar cells, have a high potential for improved efficiency. Due to their better cost-effectiveness, they can replace silicon-based solar cells in the market if their efficiency and stability increase. The design and development of DSSCs have involved not only experimental and laboratory work but also numerical modeling. The aim of this work is to design and numerically model dye-sensitized solar cells based on a nanostructured semiconductor layer with a wide bandgap (titanium dioxide) and zinc oxide as the electron transporter, N719 dye as the absorber layer, and PEDOT:PSS and P3HT as hole transport materials. In this research, the advanced software CAMSOL with extensive capabilities is used for the design of dye-sensitized solar cells, and the current-voltage characteristics and optical absorption of the cell are calculated, which are in agreement with experimental data.
