本研究透過回流法將奈米碳管浸泡在硝酸：硫酸體積比為1:3的溶液中，再透過抽氣過濾清除酸性溶液，最後利用烘箱乾燥完成純化奈米碳管。將奈米碳管添加至二氧化鈦漿料中，並使用刮刀法塗佈於fluorine-doped tin oxide (FTO)導電玻璃上，利用三明治法堆疊光陽極、熱塑性薄膜、背電極，完成染料敏化太陽能電池(DSSC)的製備。
在濃度0.01 wt%且三明治結構為TiO2/CNT/CNT (TCC)時，因為添加濃度的下降和結構的不同，而有著最高的電流密度7.63 mA/cm2。且隨著濃度的提高有著最小的Keff，其原因為濃度的提高，較容易形成團聚，造成電子電洞複合的情況發生，影響電池的整體效率。
研究結果發現，純化後的奈米碳管表面帶有官能團羧基(-COOH)，使奈米碳管均勻分布於電極中，而透過奈米碳管的直接傳導路徑使電子迅速傳輸，減少電子、電洞的複合，因此不會遇到眾多的晶粒邊界，讓效率提升至3.23 %。

In this study, the carbon nanotubes (CNT) were immersed in a solution of nitric acid: sulfuric acid volume ratio of 1:3 by reflux method, and then the acidic solution was removed by suction filtration, and finally the purified carbon nanotubes were completed by oven drying. The carbon nanotubes were added to the titanium dioxide slurry, and coated on the fluorine-doped tin oxide (FTO) conductive glass by a doctor blade method, and the photoanode, the thermoplastic film, and the back electrode were stacked by a sandwich method to complete the preparation of the dye-sensitized solar cell (DSSC).
At a concentration of 0.01 wt% and a sandwich structure of TiO2/CNT/CNT (TCC), the highest current density was 7.63 mA/cm2 due to the decrease in the concentration of addition and the difference in structure. And with the increase of concentration, there is a minimum Keff. The reason is that the concentration is increased, and it is easier to form agglomeration, which causes the electron hole to recombine and affect the overall efficiency of the battery.
The results show that the surface of the purified CNT has a functional group carboxyl group (-COOH), so that the CNT are evenly distributed in the electrodes, and the direct conduction path of the CNT allows electrons to be rapidly transported, reducing electrons, The combination of the holes, so it does not encounter numerous grain boundaries, increasing the efficiency to 3.23%.
