摘要： 本文合成了两个结构新颖的三芳基咪唑类化合物5(Im)和6(Bn-Im)，然后通过1，3-偶极化反应合成了C60吡咯烷衍生物7(Im-C60)和8(Bn-Im-C60)，用MS, NMR, IR 等对其结构进行了表征。初次组装了七个太阳能电池，结构分别为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和FTO/TiO2/Bn-Im-C60-CdSe /Pt，对其光电性能进行了表征，结果表明：与CdSe敏化太阳能电池相比，以Im-C60-CdSe和Bn-Im-C60-CdSe为敏化剂的电池效率分别增加了5.28%和40.08%。

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.
