Three different synthetic routes were used to synthesize different C 60 derivatives: azoalkane cycloaddition, Bingle-Hirsch reaction and Prato reaction. With different chemical structures, these three compounds have different acceptor strengths. These C 60 derivatives together with -phenyl C61-butyric acid methyl ester (PCBM) were used for fabrication of solar cells in blend with poly(2-methoxy-5-(2′-ethylhexoxy)-p-phenylene)(MEH-PPV). It was shown that photovoltaic cell performance varies with acceptor structure and the solubility of the C 60 derivatives in organic solvent. Energy conversion efficiency of one of the synthesized methanofullerene-phenyl C 61-butyric acid butyl ester (PCBB), shows better performance than that of PCBM.
