Abstract
Owing to their increased absorption of light in the visible region, [70]fullerene 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 [70]PCBM (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.
