[ 摘要 ]
本研究探討主要是設計於塑膠基板上進行DSSC太陽能電池各項特性探討，主要之研究項目有：（I）製備奈米二氧化鈦粉末，（II）網印法塗佈二氧化鈦薄膜，（III）探討燒結薄膜製程之溫度參數，（IV）探討燒結後薄膜與染料吸附後之特性，（V）測量封裝後之染料敏化太陽能電池性能。
研究探討的二氧化鈦粉末，分別為利用溶膠-凝膠法，塗佈過程是利用網印法的方式，藉由厚膜技術，將TiO2 粉末添加有機溶劑、分散劑等，調製出適合塗佈於導電ITO基板，網印法的應用較利於商業化的大量生產，塗佈後的薄膜需要燒結，以帶走有機溶劑，故討溫度的變化對於已塗佈在ITO導電基板上阻值變化，判斷燒結溫度範圍應在90-150℃之間，因為在這個溫度範圍塑膠基板不至於因為高溫而造成變形，導致TiO2 因變形而龜裂。
選用商業TiO2 粉末塗佈的薄膜，厚度約數十微米（µm），多孔性的薄膜電極應用於染料敏化太陽能電池上，需藉由染料的吸附作為光敏化劑，以增加電子傳導能力，本研究將多孔性的薄膜厚度對太陽能電池的影響，而厚度會影響光線TiO2 光催化作用。
本研究使用的反電極是使用石墨電極，當TiO2 多孔薄膜與染料敏化後之工作電極，並做TiO2膜厚對其最後對封裝完畢之太陽能電池測試其在太陽下之工作電壓電流，以分析其性能。

This research is probed into to design and carry on every characteristic discussion of DSSC solar cell on the plastic base plate, the main research project is as follows, ( I) Prepare and endure meter and oxidize the titanium powder two times, ( II) The network prints law coatings and oxidizes the titanium membrane two times, ( III) Is it frit membrane temperature parameter to make Cheng to probe into, ( IV) Probe into the characteristic after the membrane and dyestuffs are absorbed after fritting, ( V) Measure the day sensitization solar cell performance after encapsulation.
Study two probed into and oxidize the titanium powder, in order to utilize sol - gel law respectively, coating course to utilize network way to print law, by thick membrane technology, add organic solvent, TiO2 powder, modulate out and apply and distribute on conductive ITO base plate suitably, the application that the network prints the law relatively benefits the commercialized mass production, the membrane after the coating needs fritting, in order to take the organic solvent away, so demand the change of temperature to already hindering value change on ITO conductive base plate of the coating, judge and should frit in the temperature range it among 90-150 degrees Centigrade, because unlikely to cause because of being high-temperature out of shape in the plastic base plate of this temperature range, it is full of cracks because of being out of shape to cause TiO2.
Select commercial TiO2 membrane, powder of coating for use, about several of thickness (um) ,Porous membrane electrode is applied to the solar cell of day sensitization, the ones that needed with the dyestuffs absorb it as the mere sensitizer, conducted ability in order to increase electrons, research this getting porous membrane thickness impact on solar cell, and the thickness will influence the light TiO2 mere catalysis.
What this research is used uses the graphite electrode against the electrode, in TiO2 porous membrane and job electrode after day sensitization, make TiO2 to be membrane thick their test working voltage electric current under the sun their to solar cell that encapsulation finish finally correctly, in order to analyzes its performance. |
