Dye solar cell design parameter optimization using Silvaco ATHENA and ATLAS

Dye Solar Cell (DSC) is one of the third generation solar cell. It uses nontoxic material and relatively easy to fabricate. However, its conversion efficiency still needs to be improved. In this paper, DSC is simulated using Silvaco ATHENA and ATLAS. Parameters such as TiO
₂
layer thickness and electrolyte concentration are investigated. Effect of TiO
₂
morphology and additional TiO
₂
passivation layer are also studied. Properties of the parameters are extracted from literatures as the input for the simulation. Validation with published experimental works by other group is also performed. Results showed that by optimizing TiO
₂
thickness, TiO
₂
composite, electrolyte concentration and TiO
₂
passivation layer, DSC conversion efficiency can be improved up to 4.592%.
