We used acrylic acid and cyanoacrylic acid as the electron acceptor anchoring group in dye 1 and dye 2 respectively. The proposed dyes were sensitized from phenothiazine as the starting material by standard reactions and characterized by different techniques such as melting point, FTIR, 1HNMR, elemental analysis and UV-Visible spectroscopy after purification. Spectrophotometric measurements of the syntesised dyes in solution and on a TiO2 substrate were carried out in order to assess changes in the status of the dyes. The wavelength of maximum absorption for dye1 and dye 2 in solution are 499 nm and 505 nm and on TiO2 films are 523 nm and 527 nm, respectively. Finally, the proposed dyes used as sensitizer in a dye solar cell structure and their photovoltaic properties investigated. The Conversion efficiency for dye 1 and dye 2 are 2.34 and 3.07, respectively.}, keywords = {Synthesis and Application of Two Organic Dyes Based on Indoline in Dye,sensitized solar cells}, url = {https://pccc.icrc.ac.ir/article_75868.html}, eprint = {https://pccc.icrc.ac.ir/article_75868_81c2ad3557535cefbcc05004571b5b53.pdf} }
