| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The hydrogen generation using electrolysis of water is the most expected way of energy production due to unlimited solar energy and no air pollution. Dye Sensitized Solar Cell (DSSC) has attracted attention for its reasonable energy conversion efficiency and low cost fabrication. If we apply DSSC to water splitting system, high voltage over 1.23 V is needed to occur its reaction. To obtain higher voltage, several tandem DSSCs were reported. In the tandem DSSC, photo anode and photo cathode are connected in series without Pt. This structure has the potential of higher VOC compared conventional DSSC, and the much more low cost fabrication due to Pt-free structure. We have fabricated a p-type photo cathode using nickel oxide(NiO). As the sintering temperature increases, photo current density gets decreased due to the necking of NiO nano particles. On the other hand, the decrease of bare-FTO area by a high temperature sintering increases Voc. | |
