摘要

本研究目的在製備可撓式染料敏化太陽能電池，其中之光電極基板採用0.07mm之不銹鋼薄板以及0.25mm之鈦薄板共兩種基板，反電極基材則是採用0.125mm之導電塑膠。光電極將比較電泳沈積法（Eletrophoretic Deposition, EPD）與刀刮塗佈法(Doctor-Blade Method, DB)兩種製程，將商用TiO2奈米顆粒(Degassa P25)沈積於金屬基板上，形成厚度約10 ~15μm之TiO2薄膜，另外製備DSSC所需之染料則是採用N719染料，電解液採用0.05莫耳的碘加上0.5莫耳的碘化鉀，反電極則是使用濺鍍法（Sputtering Method）將Pt沉積到導電塑膠上，共沈積5、8、11、14nm等四種不同厚度。
實驗結果顯示不銹鋼基板使用電泳法沈積薄膜厚度為13μm之TiO2薄膜，搭配Pt度11nm之反電極，最後其DSSCs之光電轉換效率可達2.91％。
關鍵詞:可撓式染料敏化太陽能電池、¬二氧化鈦、電泳法、刀刮塗佈法。

The paper mainly studied the fabrication of flexible dye-sensitized solar cell (DSSC). The substrate of the photo-electrode were flexible stainless steel sheet with thickness 0.07mm and Ti sheet with thickness 0.25mm, and the counter electrode substrate adopted ITO-PET (Indium Tin Oxide, Polyethylene Terephthalate) with thickness 0.125 mm. Comparing the photo-electrode fabrication process by eletrophoretic deposition（EPD）and doctor-blade method（DB）, Comercial TiO2 nanoparticles（Degassa P25）was applied to deposited on metal substrates about 10~15μm. Furthermore, the sensitizer used for fabrication of DSSC was N719, and the electrolyte used was a mixture of 0.05M I2 and 0.5M KI. In addition, to achieve counter electrode, sputtering method was applied to deposit Pt on ITO-PET, resulting in thin film onto counter electrode with four different thickness, i.e. 5, 8, 11 and 14nm.
The experimental results showed that the TiO2 thin film fabricated by using stainless steel as substrate underwent EPD about 13μm and Pt thickness of counter electrode was 11nm . Finally, the conversion efficiency could reach as high as 2.91%.
