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 TiO2 layer thickness and electrolyte concentration are investigated. Effect of TiO2 morphology and additional TiO2 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 TiO2 thickness, TiO2 composite, electrolyte concentration and TiO2 passivation layer, DSC conversion efficiency can be improved up to 4.592. © 2016 IEEE.
