| Outline of Final Research Achievements |
Photorechargeable battery charged by VIS-photons was studied to laminate a rechargeable layer consisting a nano-composite of TiO2 and polyaniline (TP) and a photovoltaic one absorbing VIS-light such as dye-sensitized TiO2 or electrodeposited Cu2O.
For combination with the dye-sensitized TiO2, iodine redox couple, which was an essential reagent for the dye sensitization, inhibited the charge reaction and accelerated the self-discharge of TP layer. Therefore, it was difficult to combinate VIS-photovoltaic layer by dye sensitization to the TP rechargeable layer. For with Cu2O layer, fine crystals of Cu2O and ZnO were obtained by pulse electrodeposition for suitable for the VIS-photovoltaic layer. Furthermore, it was found that the TP nano-composite with 3D structure was promising for a fast-rechargeable and a versatile battery electrode.
