In previous study, we observed giant Seebeck coefficient in P3HT nanofiber aerogels. However, in this research, there was a problem that the doping state was unstable, and the TE performance rapidly deteriorated. Therefore, we performed a novel doping method using DBSA and freeze-drying. In this study, the thermoelectric properties and the stability of doping state under DBSA doping were discussed as compared to the conventional method.
