Resonant Electron Transfer in Collisions between Two Fullerene Ions

Solution-processed fullerene-based organic Schottky junction devices for large-open-circuit-voltage organic solar cells

A solution-processed fullerene-based organic Schottky junction photovoltaic device is fabricated to produce a large open circuit voltage, 0.85-0.95 V, which is higher than that of most organic bulk-heterojunction devices. A power conversion efficiency of 5% is achieved in fullerene-derivative [6,6]-phenyl-C71-butyric acid methylester-based Schottky junction devices.

Neutralization of charged fullerenes during grazing scattering from a metal surface

The neutralization of C(60)(+) and C(60)(2+) fullerenes with keV energies is studied for grazing scattering from a clean and flat Al(001) surface. From the measured shifts between the angular distributions for scattered projectiles of different incident charge, we derive image-charge interaction energies, which relate to the distances of electron transfer for C(60)(+) and C(60)(2+). These neutralization distances are in accord with a classical over-the-barrier model taking into account the image-charge effects of the Al target and the polarization of the fullerene.
