Abstract:

ZnO photoanode for dye sensitized solar cell sythesized by sol-gel spin coating method.  XRD pattern confirmed the film is crystalline  in nature and crystallite size calculated was 45.8 nm.  The grain size from SEM image of ZnO is 66.3nm.  Trnsmission of ZnO thin film was observed 75-92% in wavelength range from 400-800nm. The effieciency for  for dye loaded 6 and 12 hours  time were  0.38 and 0.44 respectively. In case of electrolytes ratio the maximum effieciency and fill factor were  0.44 and  0.49 respectively.
