In our device setup, we used Molybdenum oxide as a hole transport layer (HTL) and PDIN as an electron transport layer (ETL), both of which are well-established in the realm of organic photovoltaics (OPVs). Solar cell devices were fabricated on pre-coated indium-tin-oxide (ITO) glass substrates with a sheet resistance of 20-25 Ω/sq. The ITO glass was cleaned for 10 min in an ultrasonic bath containing de-ionized water, acetone, and isopropanol. First, the PDIN layers (3 mg/mL solution in methanol with 3% acetic acid to improve solubility) were spin-coated at 2000 rpm, without annealing. Subsequently, PM6 and Y7 materials were mixed at a 1.5:1 ratio, spin-coated at 2500 rpm using chloroform (CF) and solvent-annealed using 1,2-dichlorobenzene to have better interface morphology. Molybdenum oxide (MoO x ) of 10 nm subsequently evaporated. Finally, gold (100 nm) layers were deposited by evaporation through a shadow mask, resulting in an active area of 9.025 mm 2 . PM6(M2150A6) and Y7(M2212A) were procured from Ossila Materials. The materials used in this study were purchased and used as received without further purification.
