Studies on polymer based counter electrodes for DSSC application

Dye-sensitized solar cell provides a precisely and economically reliable alternate concept of present day energy crisis. DSSC have emerged as the next generation of photovoltaic devices, offering several advantages, including moderate light to conversion efficiency, low cost, flexible and easy fabrication. DSSC have many components that have to be optimized, are a mesoporous titania layer adsorbed with dye molecule, electrolyte and a counter electrode. In this work we focused on making polymer based counter electrodes for DSSC application. We made counter electrodes with PEDOT:PSS incorporated with MWCNTs and compared with the standard platinum counter electrode. The optical transmittance of the counter electrodes is studied to examine their possibility for use as transparent counter electrodes for DSSC application.
