Highly efficient, indium tin oxide (ITO)‐free and flexible organic photovoltaic cells are demonstrated with 10.4% power conversion efficiency (PCE) through the innovative integration of ultrathin metal film electrode, conductive fullerene interfacial layer, and efficient active blend into a microcavity‐embedded device. In addition, a high PCE of 7.21% is achieved for the upsized devices with an active area of 1 cm 2 .
