Owing to their increased absorption of light in the visible region, 70fullerene derivatives provide a high photocurrent when incorporated as the electron acceptor in thin‐film polymer photovoltaic cells. An incident‐photon‐to‐current efficiency of 66 % is obtained when 70PCBM (see picture) is used in combination with a poly(p‐phenylene vinylene). These high currents originate from an ultrafast charge transfer that occurs upon photoexcitation of either the fullerene or the polymer.
