| Abstract: | New soluble organofullerenes were synthesized by the reaction of organic amines and azides with the 60]fullerene. The comparative investigations of the IR- and optical absorption spectra of blends MEH-PPV/fullerene derivative in solutions and in films showed no ground-state interaction between the components. Photoluminescence (PL) experiments, and photocurrent-voltage measurements were performed on model photovoltaic (PV) cells. We found that PL of MEH-PPV is completely quenched by a small admixture of fullerene derivative which assumes a high efficiency of charge separation in the composite material. The photocurrent in the PV device containing fullerene derivative is two orders of magnitude higher than that in pure MEH-PPV. An attempt to observe the magnetic field spin effect (MFSE) on the photocurrent in MEH-PPV/fullerene composites was made. |
