摘要：
Three novel organic dyes containing julolidine and bithiophene derivatives were synthesized. Nanocrystalline TiO2 dye-sensitized solar cells were fabricated using these dyes. A solar-to-electric conversion efficiency of 2.95% is achieved with JK-14. We found that the power conversion efficiency was shown to be quite sensitive to the structural variations of bridging bithiophene moiety. (c) 2006 Elsevier Ltd. All rights reserved.
