本研究以N719染料敏化二氧化鈦多孔性奈米薄膜及圖案化氧化鎢奈米薄膜分別作為光電極與變色電極來製備光電致變色電池。並進一步研究各圖案化氧化鎢變色電極，如WO3，FTO/WO3，Pt/FTO/WO3，Pt/WO3電極等，對於電池著褪色之影響。相較於無Pt圖案化之電池， Pt圖案化之光電致變色電池具有最佳之著褪色效果。此Pt/WO3圖案化光電致變色電池於短路下利用照光與置於暗處來控制其著褪色之響應時間分別為40秒與220秒。此外，Pt/WO3圖案化光電致變色電池，於光照下可直接藉由短路及開路來控制著褪色，而著色及褪色響應時間分別為5及5秒 。將WO3/Pt圖案化光電致變色電池於光照下，藉由短路及開路，重覆做200次著褪色之測試後，穿透度並無明顯之改變，顯示此光電致變色電池具有良好的穩定性。本研究亦將Pt/WO3圖案化光電致變色電池串聯一可變電阻，於照光下短路著色時，藉由調變電阻值可改變電池著程度

Novel photoelectrochromic(PEC) cells have been fabricated using N719-sensitized TiO2 and patterned WO3 nanoparticle(NP) films. The effects of the patterned WO3 NP films, including pure WO3, FTO/WO3, Pt/FTO/WO3 and Pt/WO3 NP films, on the performances of PEC cells were investigated in this study. Among them, the cell fabricated using the Pt/WO3 patterned NP film possesses the superior performance. The response times for coloring and bleaching the cell under illumination and dark are 40 and 220 s, respectively. In addition, it was found that coloring and bleaching the cell are able to be achieved by short-circuited and open-circuited the cell, respectively, under illumination as well. The response times are even faster, which are 5 and 5 s, respectively. Long term stability of the Pt/WO3 patterned PEC cells was test by 200 cycles of coloring and bleaching. The cell demonstrates a very good stability. Finally, the transmittance of the colored PEC cell is variable by adjusting the variable resistance in series with the PEC cell.
