Organic solar cells (OSCs) could benefit from the ternary bulk heterojunction (BHJ), a method that allows for fine-tuning of light capture, cascade energy levels, and film shape, in order to increase their power conversion efficiency (PCE). In this work, third components PM6:Y6 PM6:BTP-eC9 BHJs are set four star-shaped unfused ring electron acceptors (SSUFREAs), i.e., BD-IC, BFD-IC, BD-2FIC, BFD-2FIC, facilely synthesized by direct C–H arylation. The SSUFREAs all show complete complementary absorption with PM6, Y6, BTP-eC9, which facilitates harvesting exciton collection. When BFD-2FIC is added as component, PCEs binary able be improved 15.31% 16.85%, 16.23% 17.23%, respectively, showing useful most effective OSCs general, increasing short circuit current (JSC) better morphology two additional benefits. PM6:Y6:BFD-2FIC exhibits 9.7% percentage PCE compared BHJ, one highest increases among reported BHJs, huge potential BHJ OSCs.

This study investigates the crucial role of charge transport layers in enhancing performance inverted organic photovoltaic cells (OPVs) through advanced numerical simulations using OghmaNano software. OPVs offer distinct advantages, including lightweight, flexibility, and potential cost-effectiveness compared to traditional silicon-based counterparts, making them pivotal for sustainable energy solutions. We evaluate efficiency (iOPVs) employing binary (PM6:L8-BO) ternary (PM6:D18:L8-BO) active layers, utilizing electron (ETLs) ZnO, TiO 2 , SnO hole (HTLs) such as MoO 3 PEDOT, WO . Results highlight ZnO with a 15 nm-thick layer combined HTL achieving an impressive 18.89% devices, demonstrating effectiveness materials blends. The demonstrates that or ETLs can compete effectively ETLs, particularly when used at thinner thicknesses, offers alternative fabrication methods. It suggests thin ETL (15 ± nm) could significantly enhance iOPV devices. Simulations are optimizing device configurations enabling rapid prototyping cost-effective exploration material combinations architectures. These play critical balancing carrier generation efficiency, collectively maximizing performance. Overall, underscores optimized thicknesses advancing OPV technology by refining manufacturing processes accelerating adoption
