English Abstract

Aim of this research is theoretical investigation of the electronic transfer through the dye-semiconductor contacts solar cell devices according to the calculation the electronic transfer rate constant.

Postulate of quantum mechanics is using to estimation the reorientation energy, effective free energy and rate constant at coumarin–TiO2and coumarin–ZnOsystems.

Theoretical results using to discussion the benefit of using the solar cell on the environmental depending on the calculation the electronic transfer rate cross system and that’s indicate the electric properties of solar cell and efficiency to using at cleaning electric power sources.

Electronic transfer rate constant is calculated depending on the estimation of the reorientation energy ,effective free energy , unit cell volume, penetration coefficient ,square overlapping coefficient,and temperature using a MATLAB designed program.

In both coumarin–TiO2and coumarin–ZnOsystems, the electronic transfer rate are increases with increases the reorientation energy and increases with effective free energy predictions.
