Key Points

To fabricate and evaluate an inverted organic solar cell incorporating an ultrathin calcium electron-transporting layer and a molybdenum trioxide hole-transporting layer to optimize charge extraction.
Fabricated inverted organic solar cells using a P3HT:PCBM active blend with a 1 nm calcium layer on indium tin oxide (ITO) and a molybdenum trioxide (MoO3) layer beneath a silver anode.
Simulated optical field distributions across the active blend layer to analyze how MoO3 thickness influences photocurrent generation.
Achieved a maximum power conversion efficiency of 3.55% under simulated 100 mW/cm² (AM 1.5G) solar irradiation.
Determined that 1 nm Ca optimizes the ITO work function for electron extraction, while appropriate MoO3 thickness prevents exciton quenching at the Ag anode without incurring substantial voltage loss or series resistance.
