Abstract
A high-performance organic photovoltaic cell with C70 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 MoOx as a Schottky barrier contact.
