【 摘 要 】

A  commercial  Ti-Nanoxide  was  deposited  on  In-doped  SnO2(ITO) polymer  substrates by  tape casting  technique with differentthicknesses  (7,  14  and  36μm)  to  be  used  as  photoelectrode  inflexible  dye-sensitized  solar  cells  (DSSCs).  Ruthenium  dye  wasadsorbed on each TiO2 film for 24 h. The resulting photoelectrodeswere used to form flexible DSSCs in combination with electrolyteand  counter  electrode.  The  prepared  films  were  characterized  byscanning electron microscopy (SEM) and atomic force microscopy(AFM).    Photovoltaic  parameters  like  short  circuit  current  (Isc),open  circuit  voltage  (Voc),  fill  factor  (FF)  and power  conversionefficiency (η) were evaluated for fabricated cells. The cell formedwith a TiO2 film of 14μm thickness reached the best performance.2012 JNS All rights reserved
