Solid polymeric Electrolyte based Dye-sensitized solar cell with improved stability

摘要

The impact of polymeric electrolyte was investigated over the performance of dye-sensitized solar cell made with Rose Bengal as sensitizer. Further, the selective influence of TiCl_4 treatment and pre-sensitizer deoxycholic acid on lc-TiO_2 photoanode was determined in terms of improvement in conversion efficiency of the cell. It is found that the effect of TiCl_4 treatment was comparatively more than pre-sensitization with de-oxy cholic acid towards improving the efficiency of the cell. The conversion efficiency on TiCl_4 treatment was 0.2% whereas on pre-sensitization with deoxy chollic acid it was 0.1%. The combined effect of both TiCl_4 treatment & pre-sensitization with deoxycholic acid leads conversion efficiency to 0.33%.
