Abstract

An innovative and promising approach to developing sustainable energy solutions and promoting an eco-friendly society is the use of organic solar cells. The key component for a solution-processed bulk-heterojunction organic solar cell is the photoactive layer’s embedded donor and acceptor components. This research presents seven modified molecules comprising the A–D–A type structural configuration, entitled A1–A7. All these designed moieties exhibit marvelous outcomes in optoelectronic features, including λmax and band gap, owing to non-fullerene acceptors in the terminal regions. All these compounds are computationally assessed by employing B3LYP at 6-31G (d,p) basis set using chloroform solvent. Compared to the reference molecule, the designed molecules (A1, A2, A4, A5, A6, A7) have reflected breakthrough results. The prerequisite for directing the practical application of designed acceptors is the efficient charge transfer, evidenced by coupling the J61 donor complex with the designed A5 acceptor.
