Fabrication of low-cost carbon paste based counter electrodes for dye-sensitized solar cells

We have prepared new TiO2 paste and carbon counter electrodes for the large area and low cost DSSC manufacturing applications. The carbon counter electrodes were prepared from commercial carbon paste in different sintering temperatures. The photovoltaic properties of the DSSCs made of TiO2 paste based photoanode and carbon counter electrodes showed that the sintering temperature of counter electrode strongly influences the power conversion efficiency. The carbon counter electrode sintered at 400 °C showed the conversion efficiency of 3.53% which was found comparable to the standard platinum counter electrode based DSSC efficiency of 3.96%.
