The investigation in optoelectronic parameters of the Quinizarin with semiconducting oxides at by (DFT/B3LYP) by employing a 6- 311G (d,p) basis are studies . The Electronic absorption spectrum was analyzed by TD-DFT methods and reported that wavelength is in the visible and near-UV regions. The oscillator strength; electrostatic potential confirms that was assigned to perform due to photo-induced electron transfer processes. Interaction between HOMO and LUMO of quinizarin with semiconducting oxides was explored to understand the recombination and charge transfer process involving with a bandgap of semiconductors. It shows that the effect on the process of electron injection, oxidation, and dye regeneration of DSSC applications. The photovoltaic characteristics study was performed to examine the role of charge transfer and the stability of the quinizarin dye molecule with semiconductor in the fabrication of DSSC compared with computational results.
