The temperature profile comparisons clearly indicate that higher sintering temperatures result in larger TiO2 nanoparticles. Which, in turn, result in an overall improvement on the efficiency of the solar cell. The reason being that the larger particles allow for prominent dye absorption, producing higher electron generation. The temperature upper limit is around 600 oC. As you can see, the efficiency drops suddenly due to the instability of the TiO2 nanoparticles. In conclusion, a sintering temperature between 400 oC and 500 oC will result in a highly efficient DSSC.
