染料敏化太陽能電池相較於傳統矽半導體太陽能電池具有製程簡易、成本低廉、性能穩定、可大規模生產等優點。但由於製備染料敏化太陽能電池裡的染料摻雜釕元素，由於釕元素成本高昂，所以選擇成本較低廉且取得較容易的Reactive Black 5（RB5）作為染料使用。
本研究使用二氧化鈦以絲網印刷法製程光陽極，由於絲網印刷法因可自訂薄膜面積的優點，及可有效的減少人為失誤因素，且製備薄膜的穩定性極高，故選擇使用絲網印刷法來製備染料敏化太陽能電池的二氧化鈦薄膜。之後再以醋酸銅、酞菁銅、富勒希、駢五苯，以上四種材料分別結合至RB5染料中。完成染料製作後探討吸收光譜的差異，以及RB5染料酸鹼值對染料敏化太陽能電池的影響。
研究結果表明，由醋酸銅所結合至RB5所製成的染料能有效的增加吸收光譜可見光的波段，改變酸鹼值，使其酸鹼值固定在鹼性能使RB5游離出較多的電子，從未結合醋酸銅也未改變酸鹼值其短路電流(Jsc)從0.12 (mA/cm2)提升至0.41 (mA/cm2)，由於RB5染料結合了醋酸銅能使薄膜的吸附較多染料也使薄膜不會退色，在改變酸鹼值維持鹼性時能使染料穩定且解離較多的電子，短路電流提升約241%。且優化了RB5染料的染料敏化太陽能電池電壓及電流的穩定性。

Compared to traditional silicon semiconductor solar cells, dye-sensitized solar cells have advantages such as simpler manufacturing processes, lower costs, stable performance, and the ability for mass production. However, due to the use of dyes containing ruthenium elements in the preparation of dye-sensitized solar cells, the high cost of ruthenium elements is a concern. Therefore, Reactive Black 5 (RB5), which is less expensive and easier to obtain, has been chosen as the dye for use in the dye-sensitized solar cells.
In this study, titanium dioxide was used to fabricate photoanodes via screen printing, due to the advantage of screen printing in customizing the thin film area, effectively reducing human error, and ensuring high stability in thin film preparation. Therefore, screen printing was chosen for the preparation of titanium dioxide thin films for dye-sensitized solar cells. Subsequently, copper acetate, copper phthalocyanine, fullerene, and pentaphenyl were combined separately with RB5 dye. After the completion of the dye preparation, the differences in the absorption spectrum, as well as the impact of the pH value of the RB5 dye on the dye-sensitized solar cells, were studied.
The research results indicate that the dye produced by adding copper acetate to RB5 effectively increases the absorption spectrum of visible light. Changing the pH value and maintaining it at an alkaline level allows RB5 to release more electrons. The short-circuit current (Jsc) increased from 0.12 (mA/cm2) to 0.41 (mA/cm2) even without the combination of copper acetate and a change in pH value. As RB5 dye combined with copper acetate allows the thin film to adsorb more dye and prevents the film from fading, maintaining alkalinity when changing pH value enables the dye to be stable and release more electrons, leading to a short-circuit current increase of approximately 241%. Moreover, the voltage and current stability of the dye-sensitized solar cell with RB5 dye has been optimized.
