In this paper, a solid-state dye sensitized solar cell (DSSC) based on carbon nanotubes by inserting N719 dye molecules has been designed for operating at 300oK and 330oK temperatures. The role of carbon nanotubes as hole and electron conducting agents and dye molecules as absorber of solar radiation and hole-electron pair producing agents has been discussed. After inserting N719 dye, parameters of the cell such as absorption coefficient of both layers (ZNO+SWNT, P3HT+SWNT), current density of solar cell , internal and external quantum efficiency of P3HT+SWNT layer have been obtained at 300oK and 330oK, numerically. Then, improvement value of energy conversion efficiency of the cell has been compared after inserting carbon nanotubes.

Sensitized Solar Cells

The suspension of single-walled carbon nanotubes (SWCNTs) was produced by acid functionalization process. After that, the reduced graphene oxide (r-GO) suspension was added into SWCNTs suspension in order to produce a solution of SWCNTs-Graphene mixture. The solution of SWCNTs-Graphene mixture was then deposited onto titanium dioxide (TiO2) layer as a dye monolayer in dye-sensitized solar cell (DSSC) device using drop – casting methods. Beforehand, the TiO2layer was cured with two different temperatures which was 450°C and 550°C. The electrical properties of the device, including the response and efficiency, were studied and compared with different curing temperatures.
