The effect of porosity on the current electron density at dye solar cell

In this paper, we investigate the effect of the porosity on the current electron density (je) in a modeled dye solar cell (DSC). We have used electrical model for numerical simulation of the continuity, Poisson and transparent differential equations. The results show that by decreasing the porosity, the electron current density is increased which cause to improve cell efficiency. On the other hand by increasing the porosity the tri-iodide concentration (nI3−) is decreased and iodide concentration (nI−nI−) within DSC is increased which cause to increase je and improve the performance of the cell.
