This paper addresses the optimal Dye Solar Cell (DSC) design considering parameters namely TiO2
thickness, surface
area, iodide concentration in electrolyte and TiO2
passivation layer thickness as they have influence on DSC performance.
It aims to do the research of the practical use of Taguchi method in the optimization of DSC design in order to improve
the performance of DSC. This work highlight on the integration of Taguchi method with simulation which showed that the
optimal design of DSC is 10 µm thickness of TiO2
, 90m2
/g of TiO2
photoelectrode surface area, 1 M iodide concentration
in electrolyte and two layers with 20 nm thickness of TiO2
passivation layer with efficiency of 4.59165%. All the features
of the Taguchi-based optimization were also discussed.
