چکیده
|
In this paper, we designed and synthesized free-metal dye based on indoline. the proposed dye was synthesized from phenothiazine as the starting material by standard reactions. the chemical structure of the synthesized dye was confirmed using ft-ir, 1hnmr and dsc techniques. spectrophotometric measurements of the organic dye in acetonitrile and on a tio2 substrate were carried out in order to assess the changes in the dye. maximum absorption wavelength for organic dye in solution is 453 nm and on tio2 film is 467 nm. finally, the proposed dye was used as sensitizer in a dye solar cell structure and their photovoltaic properties were investigated. the conversion efficiency for the synthesized dye is 0.92%. prog.
