A dye-sensitized solar cell (DSSC) consists of TiO₂/FTO double layer in a working electrode. We found that FTO layer showed a self-heating under a microwave irradiation and that the phenomena is acceptable in depositing a porous TiO₂ layer on FTO in producing a working electrode for DSSC. By employing this heating technique, a necking between TiO₂ particles is supposed to be enhanced to reduce an internal resistance in the cell, which leads to a higher photovoltaic performance in DSSC. We are discussing a "microwave effect" in depositing TiO₂ layer in this presentation.
