Dye-Sensitized Solar Cells Based on a Novel Fluorescent Dye with a Pyridine Ring and a Pyridinium Dye with the Pyridinium Ring Forming Strong Interactions with Nanocrystalline TiO2 Films
new-type donor-acceptorπ-conjugateddyes capable of forming a strong interaction between the electron-acceptor moiety of the sensitizers and a TiO 2 surface, fluorescentdye OH11 and pyridinum dye OH12 with a pyridine and pyridinium ring as the electron-accepting group, respectively, have been designed and synthesized as photosensitizers for use in dye-sensitizedsolarcells (DSSCs). The fluorescent dye
