Abstract

In this work, the performance of solid-state dye-sensitized solar cell (SSDSSC) with Copper (I) Iodide as a hole transport layer was investigated using SCAPS -1D simulation software. The complete simulated device structures in this project are composed of FTO/TiO2/N719/CuI/Ni. Several key parameters of HTL have been analysed to obtain the highest efficiency for SSDSSC as well as the influence of back contact. The incorporation of ETL such as TiO2, ZnO, and SnO2 also was studied. Instead of analysing the eff iciency of the SSDSSC, the recombination rate and quantum efficiency also were analysed for a few parameters. The results have proven that SSDSSC with back contact yields a better performance due to the low thickness of HTL compared to without back contact. In addition, it can also be proved that TiO2 as ETL obtained the best efficiency of 5.6%. The simulation results can be used as a guide in the fabrication process for SSDSSC employing CuI as a hole transport layer.
