Two-dimensional optical fiber-based dye-sensitized solar cell simulation: the effect of different electrodes and dyes

Abstract

A fiber-based dye-sensitized solar cell (DSSC) is a flexible wearable power resource. In order to find the real properties of the device, this system needs to be simulated. The 2-D optical fiber-based dye-sensitized solar cell is simulated by the finite element method (FEM) in order to explore the effects of $$\hbox {TiO}_{2}$$ nanorod and nanoparticle electrodes thickness and also the effects of different dyes on short-current density and efficiency of the cell. DSSCs with $$\hbox {TiO}_{2}$$ nanorod electrodes had higher short-circuit current and efficiency due to higher electron mobility than those with $$\hbox {TiO}_{2}$$ nanoparticle electrodes. The efficiency of DSSCs made by N719 was higher than that of DSSCs with different other dyes, due to better light absorption and lower rate of recombination.
