摘要

本研究主要以探討不同型態TiO2 的薄膜電極應用在染料敏化太陽能電 池(DSSC)上為主，染料在DSSC 上是不可缺少的一層，染料吸附在薄膜電 極上的多寡會直接影響DSSC 的效率，所以本篇將對不同表面型態薄膜電 極吸附染料的情況加以研究與討論。 在電極的製作方面，首先選取需要的ITO 玻璃再以同樣的參數分別完 成TiO2 薄膜的製備，已鍍好的薄膜再以450 oC 的退火處理使 TiO2 薄膜為 我們所需要的Anatase 晶相薄膜。三種不同的薄膜分別為完整薄膜型態、 凹槽型態、柱狀型態，凹槽和柱狀型態皆是用黃光顯影蝕刻所製作完成。 做好的電極在去做XRD、SEM、UV 吸收光譜、接觸角、穿透率等量測， 最後再把電極浸泡在染料中使吸收光帶變寬在與白金備電極結合，正負電 極間注入電解液這樣就完成了染料敏化太陽能電池的製作。 本研究對電極表面積的測試，對日後研究DSSC 的染料吸附過程中對 不同參數的變化之參考與導引可提供參考值，在電極尺寸上也有大大的提 升。

The main purpose of this research is to investigate the effect of applying
different types of the TiO2 thin film electrode on dye-sensitized solar cell
(DSSC). The dye is the essential element for the thin film, and its amount
will directly affect the efficiency of the DSSC. Therefore the thesis will
discuss the situations of the dye-absorption for different type of the thin
film surfaces
In making the electrodes, we choose ITO glass of the same index to grow
the thin film. Then we anneal the thin film around 450 OC to obtain
Anatase crystal phase of . TiO2.
The 3 different types of thin films are complete, concave slot, cylinder . The
concave and cylinder ones are made through etching of yellow light. Then
the electrodes will be processed by XRD, SEM,UV light absorption, contact
angle and measuring the transparency. Finally the electrodes are put in the
dye to widen the light absorption area and put the platinum contact. We
then inject the electrolyte in between the electrodes to complete the
production of the dye-sensitized solar cell.
Our results in measuring the surface area of the electrodes provide the
a reference scheme for future research on the various parameters in
making the solar cell, also promote the production of the large size DSSC.
