## 6 Conclusions  
In order to realize a solar cell with flexible, elastic and extensible properties, we fabricated a solar cell using the conventional principles of an electrolyte system in wet-type or dye-sensitized solar cells as a consecutive study of the first report. The photovoltaic effect was accomplished with electrochemical photolysis by the combination of water and TiO\({}_{2}\), referring to the Honda-Fujishima effect, and by utilizing electrolytically polymerized MCF rubber, with a magnetic field associated with the creation of magnetic clusters. MCF rubber solar cell is defined by the synthesis of a dye-sensitized solar cell and an organic thin-film solar cell as well as a tandem-type solar cell. The wet-type MCF solar cell rubber was produced via the synthesis of TiO\({}_{2}\) particles, and MCF rubber with NR-latex and MCF through compounding of MF and Ni particles, dye, and electrolyte. The photovoltaic- and piezo- effects were generated as the total transmission of electrons and built-in voltage in each of the  
Figure 19: Change in the piezoresistance by the position of the cathode for wet-type MCF rubber solar cell electrolytically polymerized under a magnetic field: “without magnet” indicates the position between the regions that are influenced by the permanent magnet at electrolytic polymerization; “with magnet” indicates the position influenced by the permanent magnet at electrolytic polymerization. In the figure, positions 1–4 of the applied magnet at electrolytic polymerization are also shown. The ordinate in the figure presents specific resistance values at non-irradiation. microscopic sections, which served as a mechanism based on the principle of ordinary solid-state dye-sensitized solar cell and the photoreaction process. The wet-type MCF rubber solar cell created both photovoltaics and piezoelectricity. In the present report, the effects of electrodes distance as well as the simultaneous existence of tension and compression on the photovoltaics were evaluated. We classify the main accomplishments of this study as follows: As for Section 3:  
* It was determined that the photoelectricity of wet-type MCF rubber solar cell is larger than that of the dry-type. Even if the MCF rubber is dry due to the electrolytic polymerization, photovoltaic- and piezo-electricity can be generated as long as dye and electrolyte are deposited next to the MCF rubber. MCF rubber solar cell can be used repeatedly by depositing electrolyte and dye. Therefore, it can be considered to have both states of dry and wet rubber and is effective for long-term use. The creation of a flexible, elastic, and extensible solar cell could generate many new engineering applications in the fields of robotics, etc. Therefore, MCF rubber solar cells can be expected to improve the daily lives of individuals. Incidentally, there is yet room for improvement in the kind of electrolyte and liquid dye in the quest to develop higher generated power. * Increasing change in resistance by irradiation, results in an increase in photoelectricity. However, there is no correlation between photoelectricity and specific resistance as piezoresistive resistance. * PSCERs are also feasible for use as a rubber-type solar cell. However, PSCER is harder than MCF rubber. As for Section 4:
* Changes to the photocurrent density and built-in current density by elongation were increased by electrolytic polymerization. By increasing elongation under constant pressure, the photocurrent density and built-in current density decreased; however, increasing the compression under constant elongation rate led to an increase of their values. * For elongated MCF rubber solar cells, the photocurrent density and built-in current density were larger with magnetic clusters than without. By increasing compression under a constant elongation rate, the photocurrent density and the built-in current density decreased. * Changes in photocurrent density and built-in current density by elongation were larger than in the plastic region.
