Abstract
This study demonstrates that FAPbI₃ perovskite quantum dot (PQD)-based electron transport layers (ETLs) significantly enhance the efficiency and stability of organic solar cells (OSCs). The PQD ETL extends light absorption from UV to NIR, complementing the PM6:Y6BO active layer, while Förster resonance energy transfer (FRET) boosts exciton generation. The dipole moment of PQDs aligns interfacial energy levels, facilitating charge transport and increasing PCE from 15.4% to 18.0% ($J_{SC}$ from 25.4 to 28.9 mA cm⁻²). The device achieved an EQE of 88% at 570 nm with a 99.0% charge dissociation probability. Notably, PQD-based cells retained 85% of their initial PCE after 16 days, outperforming reference devices. These results highlight PQDs as multifunctional ETL materials that synergistically optimize light harvesting and operational durability.
