Abstract

In this study, seven new molecules (OA1–OA7) were introduced with the goal of enhancing the photovoltaic efficiency of solar cells. All these molecules were evaluated by using density functional theory (DFT). All the designed molecules have shorter band gap and higher values of λ max than the reference. For confirming the charge mobility, the optoelectronic characterization has been carried out by densities of states (DOS), transition density matrix (TDM), molecular electrostatic potential (MEP) and reorganization energy. The V oc values in designed molecules were also improved. The stability of designed molecules was also confirmed by the analysis of non-covalent interactions (NCIs). These results elaborate on the superiority of these novel-designed molecules over pre-existing (R) molecule as potential blocks for better organic solar cell applications. In this work, a series of seven new molecules (OA1 to OA7 …
