| dc.description.abstract | Highly porous dye sensitized Ti02 thin film solar cells have been prepared hy the sol
gel process. Sensitization was achieved by use of anthocyanin pigment extracted from delphinidin
purple and cyanidin 3-5 diglucose (C35D). Sensitization was also studied on ruthenium complex
Rul. * sensitization dye. Dye sensitized photoelectrodes have exhibited broad transmission minimum
ill the visible range. Solar cells fabricated from these electrodes gave overall conversion efficiencies
of 3.16% for delphinidin purple and 2.97% for C35D. RuL dye sensitized solar cell gave 4.84%. The
cells' stability performance in terms of photovoltage was found to drop with lime of exposure.
However the cells still exhibited 1-V characteristics over a long period (six months) of study. | en |
