本文探討以鍍有ITO透明導電膜的可撓式基板，進行染料敏化太陽能電池製作及特性分析。首先將此透明導電基板，用可溫控烘烤爐(oven)以不同時間與溫度，做低溫退火的處理，並用電性量測設備(KEITHLEY 4200)做電阻量測，再以頻譜分析儀（Jasco V-550）於350nm~900nm的波段下，做透光率量測。
文中並探討製程中，碘化鉀與碘化鋰為電解液之濃度，及封裝膠體等因素，分別對染料敏化太陽能電池效率，及對鋁箔，或ITO電極的影響，進行比較分析。獲知製作染料敏化太陽能電池的較佳方法，是用丙酮超音波萃取葉綠素60分鐘，以碘化鉀與碘之比例為10:1之電解液，及氰基丙烯酸乙酯之封裝材料。而組裝完成之葉綠素染料電池，經過八種波長光源測試，發現對紅光與藍紫波段的光線，吸收效率較佳。

In this paper we use deposited ITO transparent conductive films as flexible substrates to make dye-sensitized solar cells and analysis. The processes of fabrication are as follows: First, placing the flexible substrates in the oven with different times and temperatures for low temperature annealing. Then measuring both the resistance by KEITHLEY 4200 and transmittance by spectrum analyzer（Jasco V-550）in the 350nm~900nm wavelength.

The next is to analyze KI, LiI electrolyte concentration, and encapsulated colloidal to the efficiency of the dye-sensitized solar cells, as well as the impact on the aluminum foil and ITO electrode. The chlorophyll is firstly dissolved in acetone and then extracted by ultrasonic vibration for 60 minutes. The better performance is with electrolyte concentration as KI: I = 10: 1, and using ethyl cyanoacrylate as packaging materials. After testing by eight bands of light, we found the performance of the accomplished chlorophyll dye-sensitized solar cells is more efficient in the red and/or blue-purple bands.
