英文摘要	Three dyes, 2-cyano-3-[2-(4-{2-[4-N, N-bis (4-methylphenyl) aminophenyl] vinyl}-phenylamino)-pyrimidin-5-yl]-acrylic acid (MTPA-Pyc), 2-cyano-3-(4-{2-[4-N, N-bis (4-methylphenyl) aminophenyl] vinyl}-phenyl)-acrylic acid (MTPAcc), and 2-cyano-3-[4-{2-[4-N, N-bis (4-methylphenyl) aminophenyl]-acrylic acid(MTPAc), that have different aspect ratios were studied for their performances as sensitizer in a dye sensitized solar cell (DSSC). The effects of solvent, the amount of dye molecules adsorbed on the surface of TiO2, and dye aggregation were investigated. The results show that MTPAcc has the most suitable aspect ratio among the three dyes with the highest and best photovoltaic properties. Polariry of absorption solvents can influence not only the absorbed amount of dyes at TiO2 but also the dye aggregation. MTPA-Pyc with a large aspect ratio exists in H-aggregation in tolene and tetrahydrofuran, whereas J-aggregation in acetonitrile. MTPAcc was found with high absorption amount at TiO2 but without aggregation, resulting in the best photovoltaic properties of corresponding DSSC with the incident photon-to-current efficiency(IPCE) of 84% at 490 nm and the photoelectric conversion efficiency (eta) of 5.72%. Therefore, the aspect ratio of dye sensitizers is significant for the photovoltaic properties of DSSC.
