      Abstract<\/span><\/h3>\n

      In this thesis, a theoretical model for electron transport rate approach has been used to study the Electron Transfer (ET) properties in non-homogeneous N3-MgO and\/or SnO2 systems. The process at the interface of sensitizer molecule Dye N3 contact with MgO and\/or SnO2 semiconductors materials are studied using a quantum model. We present the characteristic of ET at sensitizer N3 molecule dye contact to MgO and SnO2 semiconductors due to calculate the electronic transfer rate and transition energy using theoretical model. The transition energy and ET rate in N3\/MgO and N3\/SnO2 devices are important factors in modifying the efficiency in solar cell applications. The effects of the transition energy, driving force, potential, and coupling strength on the ET are presented. The calculations have been performed using the quantum transition theory and molecular mechanics level, based on alignment of molecule energy levels with conduction energy levels of semiconductor. Different solvents 1,2-Dimethoxyethane, Ethanol, Methanol, Chlorobenzene, 2-Methoxyethanol, Pyridineand N,N-Dimethyl formamide are taken as a polar media for N3- MgO and\/or SnO2 devices. The transition energy is determined by the donor-acceptor scenario, depending on the radii of N3 and MgO or SnO2, the dielectric constant, and the refractive index of the solvents. The transition energy of the charge carriers increased with increasing the dielectric constant and decreasing the refractive index of the solvents.\u00a0 In addition, the transition energy is strongly related to the refractive index and the dielectric constant, and it is increased with increasing the dielectric constant and decreasing the refractive index. The electronic rate increased with increasing the transition energy and both the N3- MgO and N3 – SnO2 devices show the maximum rate with methanol solvent, while it has minimum rate with Chlorobenzene solvents. Also, the electronic rate increased with decreasing the driving force energy and increasing the coupling strength. However, with increasing the coupling and ET rate, the driving energy is going to decrease.\u00a0 It can be shown that the ET process played a signi\ufb01cant role in the characteristics of N3\/MgO and N3\/SnO2 systems. The results show that the rate of ET is the highest for N3\/MgO device compare to the lowest rate for N3\/SnO2 devices. The calculation of transition energy and ET rate reveals that solvent has good media for the ET process in both system devices. The interplay between the energy levels between sensitized N3 and MgO interface with good polar media indicate the higher electronic rate of the N3\/MgO<\/span><\/h3>\n

      Conclusion<\/span><\/h3>\n

      Analysis of the calculation results shows that the electrons transfer rate is highest with the N3\/MgO device assigned to the alignment two energy levels of N3 and MgO. The estimation of the transition rate of the electrons shows that the Methanol solvent with both systems is large. It reveals that Methanol solvent is the best media to electron transfer process in both devices. The electronic transfer rate of the N3\/MgO device is highest compare with N3\/SnO2 devices for all solvents .Higher electronic transfer rate of the N3\/MgO indicates the alignment of energy levels for both sensitizer dye molecule N3 and MgO semiconductor with good polar media.<\/span><\/h3>\n
