Keywords:
Concentration, Efficiency, N3-Ruthenium, ZnS, DSSCAbstract
In this work, the effect of concentration on efficiency can be studied based on theoretical approach for N3 dye contact ZnS semiconductor based on dye sensitized solar cells DSSCs . The impact current density based on transition energy, , atomic density, length of charge, concentration as well as polarity of both N3 -ZnS system on the electronic transport process. The chemical Ethanol solvents using a polar media with N3 dye –ZnS semiconductor system. The current density component is evaluated relative to transition energy, driving energy, potential and coupling parameters. The strength coupling and concentration on the current density behavior can be discussion in N3-ZnS devices, that's reflected in the electronic transport results.The current density results reveal the behaviour of current density has been strongly affected by the concentration, it determine the efficiency of N3-ZnS devices. The electron transfer ability has been limited current density due to transition energy, driving force and potential. The efficiency, influenced by the carrier concentration increases of N3-ZnS devices ,it plays a significantly in the increases current density as well as limited the electrical properties of N3-ZnS devices. Specifically, the overlapping coupling between N3 dye and ZnS was influenced on the electronic current density.In general, the increases in concentration from to is favorable and increases efficiency from 4.09 to 4.448 ,it suggests that N3 dye a suitable contact for ZnS -based DSSCs devices.
