This work has been done to study the barrier potential and charge trapping effect of two organic devices which comprises Phenosafranin and Crystal Violet dye respectively and to estimate the influence of Titanium Dioxide (TiO2) nanomaterials in particle form on these two parameters. This paper also shows the correlation between the charge trapping and barrier potential for both of these devices. Spin coating techniques are used to prepare these two devices. To estimate the barrier potential, the current-voltage characteristics of these devices have been analyzed. Barrier potential of both these devices comprising of Phenosafranin and Crystal Violet dyes shows decrease in value from 0.81 eV to 0.44 eV and 0.80 eV to 0.43 eV respectively under the influence of Titanium Dioxide nanomaterials. Norde method has been employed to check the consistency of these values of barrier potential which also shows the decrease in value for both these devices from 0.83 eV to 0.47 eV and 0.83 eV to 0.45 eV respectively due to the incorporation of nanomaterials. Presence of traps affects the barrier potential resulting in lowering of flow of charge. By using G (V) – V plot, it has been shown that the presence of Titanium Dioxide nanomaterials improve the trap-filling process which in turn reduces barrier potential at the interface of metal – organic dye for both these devices. Improvement of charge injection process occurs at the interface of metal – organic layer due to reductions of charge trapping effect and barrier potential. |
