Theoretical Calculation of Efficiency Solid-State Zinc Oxide Solar Cells Using Indoline-Based Organic Dyes

Abstract

In this research, the quantum transition theory of the electronic transfer process was applied to calculate and study the efficiency of sensitive contact of Indoline organic dye with zinc oxide in solar cells. Electrons move from the excited state of indoline of the dye to the conduction band state of Zinc oxide to produce the current density of Dye-sensitized solar cells "DSSCs", and the energy levels of indoline and ZnO in the heterojunction device surrounded by 1-butanol solvent media must be continuous.The current density, fill factor, and efficiency of D102-ZnO devices were calculated at two carrier concentrations from 1.65 ×10^23 1/m^3 to 4.65 ×10^23 1/m^3and strength coupling in range〖[ 0.75×10^(-1)≥|〈o_EC 〉|〗^2≥0.05×10^(-1) ]〖 |eV|〗^2Increasing the characteristic carrier concentration led to an increase in the current density of the indoline dye with ZnO-based Dye-sensitized solar cells DSSC resulting in increases in the computational efficiency from 4.767% to 13.95% at a limited reorganization energy of 0.586 eV with a maximum current density from 30.2862 (mA/〖cm〗^2) to 85.354 (mA/〖cm〗^2).
