All-organic dye molecules, compared to the commercially-available ruthenium-based complexe type, hvae the advantages of high absorption coefficient, the designable and metal-free. We made use of the Vilsmeier-Haack reaction, bromination, Kumada coupling reaction, Suzuki coupling reaction and Knoevenagel condensation reaction for the photosensitive organic dye molecules. We chelated titanium dioxide nanoparticles by the groups of cyanoacetic acid. And then Optical, electrical and photoelectric conversion efficiency were measured. The optimal efficiency of DSSCs reaches to 0.34% for MTPA1 dye. In addition, We fabricated all-solid-state dye-sensitized solar cells and used Poly(3-hexylthiophene) as the Hole Transfer Materials. We compared the photoelectric conversion efficiency of the market organic dye (N3, D131 and D149) with the inorganic dye (Sb2S3).The optimal efficiency of DSSCs reaches to 2.48% for N3 dye.
