A high‐performance organic photovoltaic cell with C 70 as the sole absorber , mixed with 1,1‐bis‐(4‐bis(4‐methyl‐phenyl)‐amino‐phenyl)‐cyclohexane (TAPC), is fabricated and demonstrates a power conersion efficiency of 5.2%. With fullerene as the acceptor, high open‐circuit voltages are achieved using a donor–acceptor bulk heterojunction with a low concentration of donor in conjunction with MoO x as a Schottky barrier contact.
