本論文發展一具有太陽光熱增強性能之透明可撓式全固態超級電容器。首先，分別以多元醇法與水熱法合成銀奈米線(AgNWs)和氧化鈉鎢(NaxWO3)奈米線。其次，將銀奈米線塗佈在聚對苯二甲酸乙二酯(PET)薄膜上，然後再將氧化鈉鎢奈米線與聚(3,4-乙撐二氧噻吩)：聚苯乙烯磺酸(PEDOT:PSS)依序塗佈其上。所得透明可撓式超級電容器電極可展現電容特性，在1.0 M H2SO4中，其面電容在電流密度0.15 mA cm-2時為3.255 mF cm-2。最後，以上述電極為負極，塗佈PEDOT:PSS之PET為正極，PAA/H2SO4為膠態電解質，組成透明可撓式非對稱型全固態超級電容器。其具有54.9%之光透過率及顯著的太陽光熱增強電容特性，在太陽光照射下，其面電容增強17.7%，由0.282提升至0.332 mF cm-2。此增強效應歸諸於氧化鈉鎢照射太陽光時因光熱轉換引起溫度上升而使離子擴散速率提高所導致，進一步的動力學研究確認了此太陽光熱增強之電容主要係由擴散限制程序所貢獻。此外，能量密度和功率密度皆可藉太陽光照射而提升。在未照光與照射太陽光下，經2000次的充放電循環後，其電容分別保留初始值之80%與70.1%。所有結果證實本研究所發展 之透明可撓式全固態超級電容器具良好穩定性及顯著的太陽光熱增強電容性能。

In this thesis, a transparent flexible all-solid-state supercapacitor with solar thermal-enhanced performance was developed. Firstly, silver nanowires (AgNWs) and sodium tungsten oxide (NaxWO3) nanowires were synthesized by polyol and hydrothermal methods separately. Secondly, AgNWs were coated on polyethylene terephthalate (PET) film. Then, NaxWO3 nanowires and poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) were coated on it sequentially. The resulting transparent flexible supercapacitor electrode could exhibit the capacitive property. Its areal capacitance was 3.255 mF cm-2 in 1.0 M H2SO4 at the current density of 0.15 mA cm-2. Finally, the transparent flexible asymmetric all-solid-state supercapacitor was fabricated using the above electrode as the negative electrode, PEDOT:PSS-coated PET film as the positive electrode, and PAA/H2SO4 gel as the electrolyte. It had a transmittance of 54.9% and a significant solar thermal enhanced capacitive property. Under solar illumination, its areal capacitance was 17.7% enhanced, from 0.282 to 0.332 mF cm-2. This enhancement effect could be referred to the increased ion diffusion rate which was resulted by the raising of temperature via the photothermal conversion of NaxWO3 under solar illumination. The further kinetic study confirmed that the solar thermal-enhanced capacitance was mainly contributed by the diffusion-limited process. Moreover, it was found that both the energy density and power density could be enhanced by solar illumination. Also, after 2000 charge/discharge cycles under the conditions without and with solar illumination, this supercapacitor showed 80% and 70.1% retention, respectively. All results demonstrated that the transparent flexible all-solid-state supercapacitor developed in this study had good stability and significant solar thermal enhanced capacitive performance.
