Rose bengal sensitized ZnO photoelectrode for dye sensitized solar cell: Optimizing the performance
Two step methods have been used for the deposition of ZnO porous films onto a fluorine doped tin oxide coated glass substrate, involving spin coating, followed by the doctor blade. Deposited ZnO films were sensitized with rose bengal (4, 5, 6, 7-tetrachloro- 2′, 4′, 5′, 7′ tetraiodofluorescein) dye and has been used as a photoanode in a dye sensitized solar cell (DSSC). Performances of DSSCs were studied at a different dye sensitization time. As a consequence, enhancement of power conversion efficiency from 0.83% to 1.90% has been observed. The morphology of films is characterized by scanning electron microscopy. Electrochemical impedance spectroscopy has been used to understand the electron transfer at the interfaces.
