Crystalline Organization of a Methanofullerene as Used for Plastic Solar-Cell Applications


  • The work of X. Y. forms part of the research program of the Dutch Polymer Institute (DPI). This investigation was also financially supported in part by the Dutch Ministries of EZ, O&W and VROM through the EET program (EETK97115).


Crystalline organization of a methanofullerene, [6,6]-phenyl C61 butyric acid methyl ester (PCBM), as achieved in various thin-film deposition techniques, is reported. Mechanically stable, and thus self-supporting, thin films obtained via fast solvent evaporation techniques are found to be composed of densely and homogeneously distributed PCBM nanocrystals with various crystallographic orientations, as shown schematically in the Figure.
