First, We report a simple method for the preparation of the size tunable TiO2 sphere from titanium (IV) isopropoxide and nonionic surfactant colloids (triton X-100) as the template. The synthetic procedure is easy to control by changing the Ti/H2O ratios in the process of evaporation-induced self-assembly. We are able to tune the size of sphere TiO2 particles with diameters of 500 nm, 700 nm, and 1100 nm, named as TiO2-500, TiO2-700 and TiO2-1100. They are suitable for the fabrication of DSSCs with a comparable efficiency to the commercial photocatalyst P25. The three different TiO2 sphere size were applied as a scattering overlayer on a transparent nanocrystalline TiO2 film, bi-layered dye-sensitized solar cells (DSSCs) have been fabricated. In second part, SiO2-TiO2 composite has been reported, which uses nonionic surfactant colloids (triton X-100) as the template as a template, a titanium (IV) isopropoxide and Tetraethoxysilane as a titanium and silica source by evaporation-induced self-assembly. The SiO2-TiO2 composite can be easily shaped. The synthesized SiO2-TiO2 composite were then applied as the as a scattering overlayer on a transparent nanocrystalline TiO2 film, bi-layered dye-sensitized solar cells (DSSCs) have been fabricated. As a result the photovoltaic conversion efficiency (η) of DSSC was improved with our materials. In addition, we synthetize C-TiO2 composite by the same method. It has been investigated as a counter electrode for dye-sensitized solar cells.目錄………………………………………………………………………………......Ⅰ 圖目錄………………………………………………………………………………..Ⅲ 表目錄………………………………………………………………………………..Ⅴ 第一章 緒論………………………………………………………………………...1 1.1 前言………………………………………………………………………1 1.2 太陽能電池簡介…………………………………………………………...2 1.2.1矽太陽能電池……………………………………………………….4 1.2.2 薄膜太陽能電池…………………………………………………... 6 1.3有機太陽能電池…………………………………………………………....7 1.3.1 染料敏化太陽能電池………………………………………………8 1.3.2 染料敏化太陽能電池工作原理…………………………………....8 1.3.3太陽能電池-電壓輸出特性………………………………………..11 1.3.4染敏化太陽能電池元件結構……………………………………...13 第二章 中孔性材料簡介…………………………………………………………....22 2.1 中孔洞材料之發展……………………………………………………….22 2.2 中孔洞氧化矽SBA-15…………………………………………………...23 2.2.1 SBA-15簡介……………………………………………………….23 2.2.2 SBA-15合成機制…………………………………………………23 2.3 實驗原理…………………………………………………………………24 2.3.1溶膠凝膠法(sol-gel method)………………………………………24 2.3.2自組裝法(self-assembly)………………………………………….26 2.3.3揮發誘導自組裝法(evaporation-induced self-assembly, EISA)…29 第三章 實驗儀器……………………………………………………………………32 3.1粉末X-光繞射(Powder XRD)…………………………………………….32 3.2氮氣等溫吸附/脫附(N2 adsorption/desorption…………………………32 3.3穿透式電子顯微鏡(TEM)………………………………………………33 3.4場發射掃描式電子顯微鏡(SEM)………………………..34 3.5熱重分析儀………………………………………………………………..34 第四章 製備可調控TiO2粒子半徑及其敏化太陽能電池運用…………35 4.1 簡介………………………………………………………………………35. 4.2 實驗方法……………………………………………………………….37 4.2.1 顆粒直徑可調式二氧化鈦粉末製備……………………………37 4.2.2 工作電極漿料配…………………………………………………37 4.2.3敏化太陽能電池元件之製備…………………………………….39 4.3 樣品鑑定及染敏化太陽能電池效率測試……………………………41 4.3.1 場發射掃描式電子顯微鏡影像 ( FESEM)……………….41 4.3.2 氮氣等溫吸附與脫附曲線(BET)及X射線繞射光譜(XRD)…….44 4.3.3球狀TiO2形成機構示意圖………………………………………48 II 4.3.4 UV-VIS測試結果………………………………………………….49 4.3.5染料敏化太陽能電池測試結果…………………………………...50 4.4 結論……………………………………………………………………….53 第五章 製備TiO2及SiO2複合物粒子及其敏化太陽能電池運用……………….54 5.1 簡介……………………………………………………………………….54 5.2 實驗方法………………………………………………………………….58 5.2.1 TiO2/SiO2複合物粒子製備……………………………………….58 5.2.2 工作電極漿料配製………………………………………………..60 5.2.3敏化太陽能電池元件之製備……………………………………...60 5.3 結果與討論……………………………………………………………….62 5.3.1 場發射掃描式電子顯微鏡影像 ( FESEM )……………………..62 5.3.2能量分散光譜儀…………………………………………………...64 5.3.3 氮氣等溫吸脫附…………………………………………………..67 5.3.4球狀TiO2-SiO2 composite形成機構示意圖……………………..68 5.3.5染料敏化太陽能電池測試結果…………………………………...69 5.4 結論……………………………………………………………………….71 第六章 製備Carbon-TiO2複合物粒子運用於敏化太陽能電池對電極…………72 6.1 前言……………………………………………………………………….72 6.2 實驗方法………………………………………………………………….72 6.2.1 C-TiO2複合物粒子製備…………………………………………..75 6.2.2 C-TiO2漿料配製……………….………………………………….75 6.3 結果與討論……………………………………………………………….79 6.3.1場發射掃描式電子顯微鏡影像 ( FESEM………………………..79 6.3.2 氮氣等溫吸附與脫附曲線(BET)…………………………………81 6.3.3球狀C-TiO2 composite形成機構示意圖…………………………83 6.3.4染料敏化太陽能電池測試結果…………………………………...84 6.4 結論……………………………………………………………………….864357946 bytesapplication/pdf論文公開時間:2019/07/07論文使用權限:同意有償授權(權利金給回饋學校)利用蒸發誘導式自組裝法染敏化太陽能電池二氧化鈦[SDGs]SDG7利用蒸發誘導式自組裝法製備二氧化鈦及其複合物並運用在染敏化太陽能電池Synthesis of TiO2 and TiO2-SiO2, Carbon-TiO2 Composites by Evaporation Induced Self- assembly and Their Applications in Dye-sensitized Solar Cellthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/261248/1/ntu-103-D97223129-1.pdf
