最後將白金/碳黑電極應用於染料敏化太陽能電池的對電極上，以FTO導電玻璃為基板時得到3.84 %的光電轉換效率，而標準白金電極製作之效率為4.53 %，以ITO-PET導電塑膠板為基板的可撓式染料敏化太陽能電池轉換效率為2.24 %，標準白金電極做出的效率為2.49 %，為了使可撓式染敏太陽能電池的壽命增長，本研究使用了膠態電解質來取代原本的液態電解質，使用白金/碳黑電極製作出來的可撓式膠態染料敏化太陽能電池的效率為1.46 %，而使用白金電極製作出來的效率為1.57 %。 This study used ethylene glycol to reduced dihydrogen hexachloroplatinate. Dihydrogen hexachloroplatinate will reduce to nano platinum and attached on the carbon black. Pt/C powder have high catalytic and high specific surface. XRD and TEM can show the difference amount of platinum adhesion. Then use the Pt/C powder to produce Pt/C electrode on the FTO and ITO-PET. SEM, four-point probe, CV and EIS analysis to compare the difference in amount of platinum adhesion, adhesion agent content and different thickness. Finally to obtain a better formula is : If used the FTO substrate, Pt/C weightratio of 20 wt%, adhesion agent content of 12 wt% and the 3 μm thickness of C4-2-1 is the better formula. If used the ITO-PET substrate, Pt/C weightratio of 20 wt%, adhesion agent content of 10 wt% and the 4 μm thickness of C4-2-1 is the better formula.
Finally, the Pt/C electrode used in dye-sensitized solar cells on the counter electrode. The photoelectric conversion efficiency on the FTO glass substrate is 3.84 %, and Pt electrode production efficiency of 4.53 %. The efficiency on the ITO-PET substrate is 2.24 %, and Pt electrode production efficiency is 2.49 %. The study used a gel electrolyte to replace the liquid electrolyte. Pt/C electrode made out of the flexible gel state dye-sensitized solar cells’ efficiency of 1.46 %, and platinum electrodes produced an efficiency of 1.57 %.
