Since the discovery of a photoinduced electron transfer from a conjugated polymer to a fullerene C60, the fullerene is often selected as the electron acceptor moiety in molecular systems for photoinduced charge transfer. Energetically, the electronic structure of fullerene is favorable to serve as a strong electron acceptor in both the ground and excited states. However, the disordered islands of polymer and fullerene formed in the actual bulk heterojunction devices limited further improvement of their efficiency. To overcome this drawback, fullerene based double-cable polymers and donor–acceptor dyads, have been synthesized. In this study, we have synthesized a soluble fullerene derivative containing a perylene moiety according to well-established reaction procedures, in which a perylene moiety is attached to fullerene through a pyrrolidine ring. The current-voltage analysis of organic photovoltaic cells with the fullerene-perylene derivative was performed using a KEITHLEY SMU 2400. |
