Dye-sensitized solar cell (DSSC) is fabricated by using screen printed titania as photoanode, quasi-solid state electrolyte and xylenol orange dye as photosensitizer. Further, the impact of blocking layer on photoanode has been analyzed in terms of change in power conversion efficiency of the cell. The selective and combined influence of blocking layer on photoanode was determined in terms of improvement in Voc, Jsc and finally conversion efficiency () of DSSC. It is found that the effect of blocking layer on photoanode increased power conversion efficiency of DSSC more than two times. Further, the use of ionic polymeric iodide/triiodide redox electrolyte imparts stability to device.
