Device stability study of dye sensitized solar cells incorporated with MWCNTs

Dye-sensitized solar cells (DSSC) or Gratzel cells have attracted extensive academic and commercial interest during the last 20 years due to their potential for low cost solar energy conversion. Dye-sensitized solar cell works on the principle similar to photosynthesis. The major parts of dye-sensitized solar cells are working electrode or photo electrode, dye, electrolyte and counter electrode. Each key components have its own importance for the conversion visible light into electricity. This work highlights studies on stability of device fabricated with different counter electrodes. The photovoltaic parameters of the prepared DSSCs were compared and tabulated. It is found that the DSSC with functionalized MWCNTs as counter electrode shows the best efficiency.
