Study and Evaluation of Charge Current Rate for Fe/ZnPc Sensitizers Molecule Interface System

Abstract

A theoretical investigation and evolution of the current rate produced in the Fe/molecule system results from charge transport interaction processes. The current flow charge rate properties of Fe metal contact with ZnPc organic sensitizers are investigated and studied based on analytical calculation and a simple quantum scenario model coupled with a semi-empirical continuum energy state. The current flow charge rate is done due to the transition energy, potential interface, driving energy, and coupling coefficient for considering Fe/ ZnPc system. The evolution of current flow charge rate for Fe/ ZnPc system with variety coupling coefficient. Fe/Zn-tri-PcNc-8 sensitized system is studied at room temperature. The flow charge rate of Fe/ ZnPc system results is found to be increasing with decreasing the transition energy and increasing the coupling coefficient. Potential at the interface is estimated according to energy absorption and transition energy. Our data shows that, at high polarity, the current flow charge rate is a smooth shift with propanol solvent compared with methanol, whereas at a higher transition energy for a system with methanol solvent. It is found that the Fe/ ZnPc system with propanol solvent has good mobility of electrons compared with methanol solvent.
