Abstract: Two aromatic substituted imidazole compounds including 4-(4,5-bis(3- nitrophenyl)- 1H-imidazole-2-yl)-3,6-biacetyl-9-ethyl-carbazole(5) and 4-(1-benzyl-4,5-bis(3-nitrophenyl)- imidazol-2-yl) 3,6-biacetyl-9-ethyl-carbazole (6) have been synthesized by the optimized Debus’ method. Fulleropyrrolidine derivatives (7) and (8) were successfully synthesized by 1,3-dipolar cycloaddition. The structure of these moleculars were identified by MS, NMR and IR. Seven solar cells were fabricated: FTO/TiO2/CdSe/Pt, FTO/TiO2/C60/Pt, FTO/TiO2/Im-C60/Pt, FTO/TiO2/Bn-Im-C60/Pt, FTO/TiO2/C60-CdSe/Pt, FTO/TiO2/Im-C60-CdSe /Pt and FTO/TiO2/Bn-Im-C60-CdSe/Pt. The result showed that the observed energy conversion efficiency of Im-C60-CdSe based solar cell and Bn-Im-C60-CdSe based solar cell are 5.28% and 40.08% respectively which were compared with CdSe QDs sensitized solar cell.
